AI-suggested

A fix is available in dulwich version 1.2.5. Users should upgrade to version 1.2.5 or later to remediate this vulnerability. Until upgraded, avoid cloning or updating submodules from untrusted repositories with recurse_submodules enabled.

Description

Dulwich versions from 0.23.2 up to but not including 1.2.5 contain a path traversal vulnerability in the submodule update functionality. This flaw allows an attacker controlling a repository's .gitmodules and gitlink entries to write files into arbitrary directories within the victim's .git directory, such as .git/hooks. Because executable bits are preserved, this can lead to arbitrary code execution when Git or Dulwich subsequently runs these hooks.
