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 git19-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
