Descriptions

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. The wincred credential helper uses a static buffer (target) as a unique key for storing and comparing against internal storage. This credential helper does not properly bounds check the available space remaining in the buffer before appending to it with wcsncat(), leading to potential buffer overflows. This vulnerability is fixed in v2.43.7, v2.44.4, v2.45.4, v2.46.4, v2.47.3, v2.48.2, v2.49.1, and v2.50.1.

Avi Halachmi discovered that Git incorrectly managed file modification constraints with Gitk. An attacker could possibly use this issue to create or write to arbitrary files on the system. Avi Halachmi discovered that Git incorrectly handled arguments when invoking the Gitk utility. If a user were tricked into cloning a malicious Git repository, an attacker could possibly use this issue to run arbitrary commands. This issue only affected Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04.
