Synopsis: Important: git security update
Advisory ID: RHSA-2023:0599-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2023:0599
Issue date: 2023-02-06

1. Summary:
An update for git is now available for Red Hat Enterprise Linux 8.1 Update
Services for SAP Solutions.
Red Hat Product Security has rated this update as having a security impact
of Important. 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 E4S (v. 8.1) - 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: gitattributes parsing integer overflow (CVE-2022-23521)
* git: Heap overflow in `git archive`, `git log --format` leading to RCE
(CVE-2022-41903)
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
