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)

* 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)
