=====================================================================
                   Red Hat Security Advisory

Synopsis:          Important: git security update
Advisory ID:       RHSA-2017:2485-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2017:2485
Issue date:        2017-08-16
CVE Names:         CVE-2017-1000117 
=====================================================================

1. Summary:

An update for git is now available for Red Hat Enterprise Linux 6.

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 Desktop Optional (v. 6) - i386, noarch, x86_64
Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch, x86_64
Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64
Red Hat Enterprise Linux Server Optional (v. 6) - i386, noarch, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64
Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, 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.

Security Fix(es):

* A shell command injection flaw related to the handling of "ssh" URLs has
been discovered in Git. An attacker could use this flaw to execute shell
commands with the privileges of the user running the Git client, for
example, when performing a "clone" action on a malicious repository or a
legitimate repository containing a malicious commit. (CVE-2017-1000117)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

5. Bugs fixed (https://bugzilla.redhat.com/):
