Moderate: git security and bug fix update

Published May 16, 2023 · Updated Oct 29, 2026

Ecosystem: AlmaLinux

Summary

Git is a distributed revision control system with a decentralized architecture. As opposed to centralized version control systems with a client-server model, Git ensures that each working copy of a Git repository is an exact copy with complete revision history. This not only allows the user to work on and contribute to projects without the need to have permission to push the changes to their official repositories, but also makes it possible for the user to work with no network connection.

Security Fix(es):

* git: On multi-user machines Git users might find themselves unexpectedly in a Git worktree (CVE-2022-24765)
* git: Bypass of safe.directory protections (CVE-2022-29187)
* git: exposure of sensitive information to a malicious actor (CVE-2022-39253)
* git: git shell function that splits command arguments can lead to arbitrary heap writes. (CVE-2022-39260)
