Monthly report about Debian Long Term Support, January 2026

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 Roucariès 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 Sánchez (DLA-4437-1), fixing multiple issues, including CVE-2025-68973 that could potentially be exploited to execute arbitrary code.
  • apache-log4j2, prepared by Markus Koschany (DLA-4444-1)
  • ceph, prepared by Utkarsh Gupta (DLA-4460-1)
  • 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.
