SCA: security update for dulwich (GHSA-9277-mp7x-85jf)

high Tenable Cloud Security Plugin ID 442449

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Dulwich is a pure-Python implementation of the Git file formats and protocols. Starting in version 0.24.0
 and prior to version 1.2.5, Dulwich's `ProcessMergeDriver` substitutes the file path (from the git tree,
 controllable by an attacker via a malicious branch) into the merge driver command via the `%P` placeholder
 and executes it with `subprocess.run(..., shell=True)`. An attacker who can cause a victim to merge an
 untrusted branch can achieve arbitrary command execution by crafting malicious file paths. Version 1.2.5
 fixes the issue. (CVE-2026-42563)

Solution

Update the dulwich library and its related packages to version 1.2.5 or later.
