(RHSA-2016:0497) Important: git19-git security update

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.

An integer truncation flaw and an integer overflow flaw, both leading to a
heap-based buffer overflow, were found in the way Git processed certain
path information. A remote attacker could create a specially crafted Git
repository that would cause a Git client or server to crash or, possibly,
execute arbitrary code. (CVE-2016-2315, CVE-2016-2324)

All git19-git users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues.
