Freexian Collaborators: Monthly report about Debian Long Term Support, May 2026 (by Santiago Ruano Rinc n)

The Debian LTS Team, funded by Freexian s Debian LTS offering, is pleased to report its activities for May.

Activity summary During the month of May, 21 contributors have been paid to work on Debian LTS (links to individual contributor reports are located below). The team released 56 DLAs fixing 877 CVEs. May was a much busier month than usual, especially due to the disclosed vulnerabilities on linux regarding Local Privilege Escalation (LPE), that included public proof-of-concept (PoC) exploits. These reports of course impacted Debian as a whole, and the situation warrants a special mention to the Kernel Team, especially Ben Hutching and Salvatore Bonaccorso, who faced the pace and released linux packages on a weekly basis. On the LTS side, the Front Desk team also triaged a significant flow of high severity CVEs. It is also important to note that Debian 12 ( bookworm ) will be handed over to the LTS Team on June 11th. If you benefit from Debian, especially during the full 5-year lifecycle, please consider subscribing as a sponsor of Debian LTS: https://www.freexian.com/lts/debian/. Moreover, Debian 11 ( bullseye ) will reach the end of the Debian LTS period on August 31st. After that, Freexian will continue the security support under the Extended LTS offer. The team published several notable updates:
  • As mentioned above, several exploitable LPE vulnerabilities in linux were published during May. Ben released the following DLAs for the Debian LTS versions:
  • exim update (DLA-4580-1), prepared by Thorsten, to address a vulnerability that may result in remote code execution.
  • gnutls28 update (DLA-4595-1) by Guilhem Moulin, fixes several vulnerabilities that may result in execution of arbitrary code, information leak, authentication bypass, among other impacts.
  • krb5 updates released as DLA-4603-1, fixing two vulnerabilities that may yield to a denial of service. Updated prepared by Emmanuel Arias
  • lemonldap-ng (DLA-4602-1), released by Abhijith PA, fixing multiple vulnerabilities
  • Two imagemagick updates (DLA-4559-1 and DLA-4609-1), prepared by Bastien Roucari s, fixing several vulnerabilities
  • openjdk-11 and openjdk-17 updates (DLA-4566-1 and DLA-4565-1), both prepared by Emilio, to fix seven vulnerabilities.
  • php7.4 update (DLA-4586-1) to fix six vulnerabilities that could result in remote code execution, information disclosure or denial of service. Update prepared by Guilhem Moulin.
  • python3.9 update (DLA-4583-1), prepared by Arnaud Rebillout, addressing multiple vulnerabilities.
Contributions from outside the LTS Team: We are greatly thankful for the contributions from people outside the LTS Team:
  • Colin Watson prepared an OpenSSH update, that was released by Santiago as DLA-4584-1.
  • Thomas Goirand handled a keystone update, whose advisory was done by Santiago and released as DLA-4611-1.
  • Christopher Obbard kindly prepared a sentry-python update, released as DLA-4612-1.
  • Christoph Goehre made two thunderbird updates (DLA-4562-1 and DLA-4582-1). As is customary, Emilio released the advisories.
The LTS Team has also contributed with updates to the latest Debian releases: Moreover, thanks to our partnership with Catalyst, it has been possible to extend the support for Samba 4.17, the version shipped with Debian 12. In May, several vulnerabilities were disclosed, and their patches were prepared by Catalyst. For Debian 12, the update was prepared by the Samba maintainer and released as DSA-6297-1.

Freexian Collaborators: Monthly report about Debian Long Term Support, January 2026 (by Santiago Ruano Rinc n)

The Debian LTS Team, funded by Freexian s Debian LTS offering, is pleased to report its activities for January.

Activity summary During the month of January, 20 contributors have been paid to work on Debian LTS (links to individual contributor reports are located below). The team released 33 DLAs fixing 216 CVEs. The team continued preparing security updates in its usual rhythm. Beyond the updates targeting Debian 11 ( bullseye ), which is the current release under LTS, the team also proposed updates for more recent releases (Debian 12 ( bookworm ) and Debian 13 ( trixie )), including Debian unstable. We highlight several notable security updates here below. Notable security updates:
  • python3.9, prepared by Andrej Shadura (DLA-4455-1), fixing multiple vulnerabilities in the Python interpreter.
  • php, prepared by Guilhem Moulin (DLA-4447-1), fixing two vulnerabilities that could yield to request forgery or denial of service.
  • apache2, prepared by Bastien Roucari s DLA-4452-1, fixing four CVEs.
  • linux-6.1, prepared by Ben Hutchings (DLA-4436-1), as a regular update of the linux 6.1 backport to Debian 11.
  • python-django, prepared by Chris Lamb (DLA-4458-1), resolving multiple vulnerabilities.
  • firefox-esr prepared by Emilio Pozuelo Monfort (DLA-4439-1)
  • gnupg2, prepared by Roberto S nchez (DLA-4437-1), fixing multiple issues, including CVE-2025-68973 that could potentially be exploited to execute arbitrary code.

  • inetutils, prepared by Andreas Henriksson (DLA-4453-1), fixing an authentication bypass in telnetd.
Moreover, Sylvain Beucler studied the security support status of p7zip, a fork of 7zip that has become unmaintained upstream. To avoid letting the users continue using an unsupported package, Sylvain has investigated a path forward in collaboration with the security team and the 7zip maintainer, looking to replace p7zip with 7zip. It is to note however that 7zip developers don t reveal the information about the patches that fix CVEs, making it difficult to backport single patches to fix vulnerabilities in Debian released versions. Contributions from outside the LTS Team: Thunderbird, prepared by maintainer Christoph Goehre. The DLA (DLA-4442-1) was published by Emilio. The LTS Team has also contributed with updates to the latest Debian releases:
  • Bastien uploaded gpsd to unstable, and proposed updates for trixie #1126121 and bookworm #1126168 to fix two CVEs.
  • Bastien also prepared the imagemagick updates for trixie and bookworm, released as DSA-6111-1, along with the bullseye update DLA-4448-1.
  • Chris proposed a trixie point update for python-django (#112646), and the work for bookworm was completed in February (#1079454). The longstanding bookworm update required tracking down a regression in the django-storages packages.
  • Markus prepared tomcat10 updates for trixie and bookworm (DSA-6120-1), and tomcat11 for trixie (DSA-6121-1)
  • Thorsten Alteholz prepared bookworm point updates for zvbi (#1126167) to fix five CVEs; taglib (#1126273) to fix one CVE; and libuev (#1126370) to fix one CVE.
  • Utkarsh prepared an unstable update of node-lodash to fix one CVE.
Other than the work related to updates, Sylvain made several improvements to the documentation and tooling used by the team.

    • cups, prepared by Thorsten Alteholz, fixes authentication bypass and denial of service vulnerabilities
    • jetty9, prepared by Adrian Bunk, fixes the MadeYouReset vulnerability (a recent, well-known denial of service vulnerability)
    • python-django, prepared by Chris Lamb, fixes a SQL injection vulnerability
    • firefox-esr and thunderbird, prepared by Emilio Pozuelo Monfort, were updated from the 128.x ESR series to the 140.x ESR series, fixing a number of vulnerabilities as well
  • Notable non-security updates:
    • wireless-regdb prepared by Ben Hutchings, updates information reflecting changes to radio regulations in many countries
There was one package update contributed by a Debian Developer outside of the LTS Team: an update of node-tar-fs, prepared by Xavier Guimard (a member of the Node packaging team). Finally, LTS Team members also contributed updates of the following packages:
  • libxslt (to stable and oldstable), prepared by Guilhem Moulin, to address a regression introduced in a previous security update
  • libphp-adodb (to stable and oldstable), prepared by Abhijith PA
  • cups (to stable and oldstable), prepared by Thorsten Alteholz
  • u-boot (to oldstable), prepared by Daniel Leidert and Jochen Sprickerhof
  • libcommongs-lang3-java (to stable and oldstable), prepared by Daniel Leidert
  • python-internetarchive (to oldstable), prepared by Daniel Leidert
One other notable contribution by a member of the LTS Team is that Sylvain Beucler proposed a fix upstream for CVE-2025-2760 in gimp2. Upstream no longer supports gimp2, but it is still present in Debian LTS, and so proposing this fix upstream is of benefit to other distros which may still be supporting the older gimp2 packages.

DebConf, the annual Debian Conference, is coming up in July and, as is customary each year, the week preceding the conference will feature an event called DebCamp. The DebCamp week provides an opportunity for teams and other interested groups/individuals to meet together in person in the same venue as the conference itself, with the purpose of doing focused work, often called sprints . LTS coordinator Roberto C. S nchez has announced that the LTS Team is planning to hold a sprint primarily focused on the Debian security tracker and the associated tooling used by the LTS Team and the Debian Security Team.

Freexian, the entity behind the management of the Debian LTS project, has been working for some time now on the development of an advanced CI platform for Debian-based distributions, called Debusine. Recently, Debusine has reached a level of feature implementation that makes it very usable. Some members of the LTS Team have been using Debusine informally, and during May LTS coordinator Santiago Ruano Rinc n has made a call for the team to help with testing of Debusine, and to help evaluate its suitability for the LTS Team to eventually begin using as the primary mechanism for uploading packages into Debian. Team members who have started using Debusine are providing valuable feedback to the Debusine development team, thus helping to improve the platform for all users. Actually, a number of updates, for both bullseye and bookworm, made during the month of May were handled using Debusine, e.g. rubygems s DLA-4163-1. By the way, if you are a Debian Developer, you can easily test Debusine following the instructions found at https://wiki.debian.org/DebusineDebianNet. DebConf, the annual Debian Conference, is coming up in July and, as is customary each year, the week preceding the conference will feature an event called DebCamp. The DebCamp week provides an opportunity for teams and other interested groups/individuals to meet together in person in the same venue as the conference itself, with the purpose of doing focused work, often called sprints . LTS coordinator Roberto C. S nchez has announced that the LTS Team is planning to hold a sprint primarily focused on the Debian security tracker and the associated tooling used by the LTS Team and the Debian Security Team.

Additional updates of ruby3.3 and rubygems were prepared for Debian unstable by Lucas Kanashiro. And finally, a highlight of our continued commitment to enhancing long term support efforts in upstream projects. Freexian, as the primary entity behind the management and execution of the LTS project, has partnered with Invisible Things Lab to extend the upstream security support of Xen 4.17, which is shipped in Debian 12 bookworm (the current stable release). This partnership will result in significantly improved lifecycle support for users of Xen on bookworm, and members of the LTS team will play a part in this endeavour. The Freexian announcement has additional details.

Additional stable updates, for tomcat10 and jetty9, were prepared by LTS contributor Markus Koschany. And, finally, LTS contributor Utkarsh Gupta prepared stable updates for rails and ruby-rack. LTS contributor Emilio Pozuelo Monfort has continued his ongoing improvements to the Debian security tracker and its associated tooling, making the data contained in the tracker more reliable and easing interaction with it. The ckeditor3 package, which has been EOL by upstream for some time, is still depended upon by the PHP Horde packages in Debian. Sylvain, along with Bastien, did monumental work in coordinating with maintainers, security team fellows, and other Debian teams, to formally declare the EOL of the ckeditor3 package in Debian 11 and in Debian 12. Additionally, as a result of this work Sylvain has worked towards the removal of ckeditor3 as a dependency by other packages in order to facilitate the complete removal of ckeditor3 from all future Debian releases.

    • openssh, prepared by Colin Watson, fixed a machine-in-the-middle vulnerability
LTS contributors Emilio Pozuelo Monfort and Santiago Ruano Rinc n coordinated the administrative aspects of LTS updates of postgresql-13 and pam-u2f, which were prepared by the respective maintainers, to whom we are most grateful. As has become the custom of the LTS team, work is under way on a number of package updates targeting Debian 12 (codename bookworm ) with fixes for a variety of vulnerabilities. In February, Guilhem Moulin prepared an upload of sssd, while several other updates are still in progress. Bastien Roucari s prepared an upload of krb5 for unstable as well. Given the importance of the Debian Security Tracker to the work of the LTS Team, we regularly contribute improvements to it. LTS contributor Emilio Pozuelo Monfort reviewed and merged a change to improve performance, and then dealt with unexpected issues that arose as a result. He also made improvements in the processing of CVEs which are not applicable to Debian. Looking to the future (the release of Debian 13, codename trixie , and beyond), LTS contributor Santiago Ruano Rinc n has initiated a conversation among the broader community involved in the development of Debian. The purpose of the discussion is to explore ways to improve the long term supportability of packages in Debian, specifically by focusing effort on ensuring that each Debian release contains the best supported upstream version of packages with a history of security issues.

    • debian-security-support, prepared by Santiago Ruano Rinc n, which formalized the EOL of intel-mediasdk and node-matrix-js-sdk
In addition to the security and non-security updates targeting bullseye , various LTS contributors have prepared uploads targeting Debian 12 (codename bookworm ) with fixes for a variety of vulnerabilities. Abhijith PA prepared an upload of puma; Bastien Roucari s prepared an upload of node-postcss with fixes for data processing and denial of service vulnerabilities; Daniel Leidert prepared updates for setuptools, python-asyncssh, and python-tornado; Lee Garrett prepared an upload of ansible-core; and Guilhem Moulin prepared updates for python-urllib3, sqlparse, and opensc. Santiago Ruano Rinc n also worked on tracking and filing some issues about packages that need an update in recent releases to avoid regressions on upgrade. This relates to CVEs that were fixed in buster or bullseye, but remain open in bookworm. These updates, along with Santiago s work on identifying and tracking similar issues, underscore the LTS Team s commitment to ensuring that the work we do as part of LTS also benefits the current Debian stable release. LTS contributor Sean Whitton also prepared an upload of jinja2 and Santiago Ruano Rinc n prepared an upload of openjpeg2 for Debian unstable (codename sid ), as part of the LTS Team effort to assist with package uploads to unstable.

Evolution of the situation In December, we have released 29 DLAs. The LTS Team has published updates to several notable packages. Contributor Guilhem Moulin published an update of php7.4, a widely-used open source general purpose scripting language, which addressed denial of service, authorization bypass, and information disclosure vulnerabilities. Contributor Lucas Kanashiro published an update of clamav, an antivirus toolkit for Unix and Linux, which addressed denial of service and authorization bypass vulnerabilities. Finally, contributor Tobias Frost published an update of intel-microcode, the microcode for Intel microprocessors, which well help to ensure that processor hardware is protected against several local privilege escalation and local denial of service vulnerabilities. Beyond our customary LTS package updates, the LTS Team has made contributions to Debian s stable bookworm release and its experimental section. Notably, contributor Lee Garrett published a stable update of dnsmasq. The LTS update was previously published in November and in December Lee continued working to bring the same fixes (addressing the high profile KeyTrap and NSEC3 vulnerabilities) to the dnsmasq package in Debian bookworm. This package was accepted for inclusion in the Debian 12.9 point release scheduled for January 2025. Addititionally, contributor Sean Whitton provided assistance, via upload sponsorships, to the Debian maintainers of xen. This assistance resulted in two uploads of xen into Debian s experimental section, which will contribute to the next Debian stable release having a version of xen with better longterm support from the upstream development team.

Evolution of the situation In November, we have released 38 DLAs. The LTS coordinators, Roberto and Santiago, delivered a talk at the Mini-DebConf event in Toulouse, France. The title of the talk was How LTS goes beyond LTS . The talk covered work done by the LTS Team during the past year. This included contributions related to individual packages in Debian (such as tomcat, jetty, radius, samba, apache2, ruby, and many others); improvements to tooling and documentation useful to the Debian project as a whole; and contributions to upstream work (apache2, freeimage, node-dompurify, samba, and more). Additionally, several contributors external to the LTS Team were highlighted for their contributions to LTS. Readers are encouraged to watch the video of the presentation for a more detailed review of various ways in which the LTS team has contributed more broadly to the Debian project and to the free software community during the past year. We wish to specifically thank Salvatore (of the Debian Security Team) for swiftly handling during November the updates of needrestart and libmodule-scandeps-perl, both of which involved arbitrary code execution vulnerabilities. We are happy to see increased involvement in LTS work by contributors from outside the formal LTS Team. The work of the LTS Team in November was otherwise unremarkable, encompassing the customary triage, development, testing, and release of numerous DLAs, along with some associated contributions to related packages in stable and unstable.

Additional contributions were made for the stable Debian 12 bookworm release by several LTS contributors. Arturo Borrero Gonzalez prepared a parallel update of nss, Bastien Roucari s prepared a parallel update of apache2, and Santiago Ruano Rinc n prepared updates of activemq for both LTS and Debian stable. LTS contributor Bastien Roucari s undertook a code audit of the cacti package and in the process discovered three new issues in node-dompurity, which were reported upstream and resulted in the assignment of three new CVEs. As always, the LTS team continues to work towards improving the overall sustainability of the free software base upon which Debian LTS is built. We thank our many committed sponsors for their ongoing support.

Freexian Collaborators: Monthly report about Debian Long Term Support, September 2024 (by Roberto C. S nchez)

Like each month, have a look at the work funded by Freexian s Debian LTS offering.

Debian LTS contributors In September, 18 contributors have been paid to work on Debian LTS, their reports are available:
  • Abhijith PA did 7.0h (out of 0.0h assigned and 14.0h from previous period), thus carrying over 7.0h to the next month.
  • Adrian Bunk did 51.75h (out of 9.25h assigned and 55.5h from previous period), thus carrying over 13.0h to the next month.
  • Arturo Borrero Gonzalez did 10.0h (out of 0.0h assigned and 10.0h from previous period).
  • Bastien Roucari s did 20.0h (out of 20.0h assigned).
  • Ben Hutchings did 20.0h (out of 12.0h assigned and 12.0h from previous period), thus carrying over 4.0h to the next month.
  • Chris Lamb did 18.0h (out of 18.0h assigned).
  • Daniel Leidert did 23.0h (out of 26.0h assigned), thus carrying over 3.0h to the next month.
  • Emilio Pozuelo Monfort did 23.5h (out of 22.25h assigned and 37.75h from previous period), thus carrying over 36.5h to the next month.
  • Guilhem Moulin did 22.25h (out of 20.0h assigned and 2.5h from previous period), thus carrying over 0.25h to the next month.
  • Lucas Kanashiro did 10.0h (out of 5.0h assigned and 15.0h from previous period), thus carrying over 10.0h to the next month.
  • Markus Koschany did 40.0h (out of 40.0h assigned).
  • Ola Lundqvist did 6.5h (out of 14.5h assigned and 9.5h from previous period), thus carrying over 17.5h to the next month.
  • Roberto C. S nchez did 24.75h (out of 21.0h assigned and 3.75h from previous period).
  • Santiago Ruano Rinc n did 19.0h (out of 19.0h assigned).
  • Sean Whitton did 0.75h (out of 4.0h assigned and 2.0h from previous period), thus carrying over 5.25h to the next month.
  • Sylvain Beucler did 16.0h (out of 42.0h assigned and 18.0h from previous period), thus carrying over 44.0h to the next month.
  • Thorsten Alteholz did 11.0h (out of 11.0h assigned).
  • Tobias Frost did 17.0h (out of 7.5h assigned and 9.5h from previous period).

Evolution of the situation In September, we have released 52 DLAs. September marked the first full month of Debian 11 bullseye under the responsibility of the LTS Team and the team immediately got to work, publishing more than 4 dozen updates. Some notable updates include ruby2.7 (denial-of-service, information leak, and remote code execution), git (various arbitrary code execution vulnerabilities), firefox-esr (multiple issues), gnutls28 (information disclosure), thunderbird (multiple issues), cacti (cross site scripting and SQL injection), redis (unauthorized access, denial of service, and remote code execution), mariadb-10.5 (arbitrary code execution), cups (arbitrary code execution). Several LTS contributors have also contributed package updates which either resulted in a DSA (a Debian Security Announcement, which applies to Debian 12 bookworm) or in an upload that will be published at the next stable point release of Debian 12 bookworm. This list of packages includes cups, cups-filters, booth, nghttp2, puredata, python3.11, sqlite3, and wireshark. This sort of work, contributing fixes to newer Debian releases (and sometimes even to unstable), helps to ensure that upgrades from a release in the LTS phase of its lifecycle to a newer release do not expose users to vulnerabilities which have been closed in the older release. Looking beyond Debian, LTS contributor Bastien Roucari s has worked with the upstream developers of apache2 to address regressions introduced upstream by some recent vulnerability fixes and he has also reached out to the community regarding a newly discovered security issue in the dompurify package. LTS contributor Santiago Ruano Rinc n has undertaken the work of triaging and reproducing nearly 4 dozen CVEs potentially affecting the freeimage package. The upstream development of freeimage appears to be dormant and some of the issues have languished for more than 5 years. It is unclear how much can be done without the aid of upstream, but we will do our best to provide as much help to the community as we can feasibly manage. Finally, it is sometimes necessary to limit or discontinue support for certain packages. The transition of a release from being under the responsibility of the Debian Security Team to that of the LTS Team is an occasion where we assess any pending decisions in this area and formalize them. Please see the announcement for a complete list of packages which have been designated as unsupported.
