Synopsis: Moderate: git security update Advisory ID: RHSA-2015:2561-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-2561.html Issue date: 2015-12-08 =====================================================================
1. Summary:
Updated git packages that fix one security issue are now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Client Optional (v. 7) - noarch, x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, noarch, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, noarch, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - noarch, 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.
A flaw was found in the way the git-remote-ext helper processed certain URLs. If a user had Git configured to automatically clone submodules from untrusted repositories, an attacker could inject commands into the URL of a submodule, allowing them to execute arbitrary code on the user's system. (BZ#1269794)
All git users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
4. Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.
