RHEL 7 : git (RHSA-2017:2004)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An update for git is now available for Red Hat Enterprise Linux 7.

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.

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) :

* It was found that the git-prompt.sh script shipped with git failed
to correctly handle branch names containing special characters. A
specially crafted git repository could use this flaw to execute
arbitrary commands if a user working with the repository configured
their shell to include repository information in the prompt.
(CVE-2014-9938)

* A flaw was found in the way git-shell handled command-line options
for the restricted set of git-shell commands. A remote, authenticated
attacker could use this flaw to bypass git-shell restrictions, to view
and manipulate files, by abusing the instance of the less command
launched using crafted command-line options. (CVE-2017-8386)
