Summary: An update for git is now available for Red Hat Enterprise Linux 8.2 Advanced Update Support, Red Hat Enterprise Linux 8.2 Telecommunications Update Service, and Red Hat Enterprise Linux 8.2 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 AUS (v. 8.2) - aarch64, noarch, ppc64le, s390x, x86_64 Red Hat Enterprise Linux AppStream E4S (v. 8.2) - aarch64, noarch, ppc64le, s390x, x86_64 Red Hat Enterprise Linux AppStream TUS (v. 8.2) - 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. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 2162055 - CVE-2022-23521 git: gitattributes parsing integer overflow 2162056 - CVE-2022-41903 git: Heap overflow in `git archive`, `git log --format` leading to RCE 6.
