-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-4610-1 [email protected] https://www.debian.org/lts/security/ Andrej Shadura May 31, 2026 https://wiki.debian.org/LTS - -------------------------------------------------------------------------
Package : git-lfs Version : 2.13.2-1+deb11u2 CVE ID : CVE-2025-26625 In Git LFS versions 0.5.2 through 3.7.0, when populating a Git repository's working tree with the contents of Git LFS objects, certain Git LFS commands could write to files visible outside the current Git working tree if symbolic or hard links existed which collided with the paths of files tracked by Git LFS. The git lfs checkout and git lfs pull commands did not check for symbolic links before writing to files in the working tree, which allowed an attacker to craft a repository containing symbolic or hard links that caused Git LFS to write to arbitrary file system locations accessible to the user running these commands. Also, when the git lfs checkout and git lfs pull commands were run in a bare repository, they could write to files visible outside the repository. The complete fix to this issue, specifically the behaviour of git lfs pull, requires a newer Git version, 2.42.0 or newer. As a workaround, support for symlinks in Git may be disabled by setting the core.symlinks configuration option to false, after which further clones and fetches will not create symbolic links. However, any symbolic or hard links in existing repositories will still provide the opportunity for Git LFS to write to their targets. For Debian 11 bullseye, this problem has been partially fixed in version 2.13.2-1+deb11u2. For a complete fix, Git 2.42.0 or newer is also required. We recommend that you upgrade your git-lfs packages.
