[RHSA-2023:2859-01] Moderate: git security and bug fix update

Tue May 16 12:00:32 UTC 2023

An update for git is now available for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AppStream (v. 8) - aarch64, noarch, ppc64le, s390x, x86_64

3. Description:

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)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
