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):
* git: arbitrary code execution via .gitmodules (CVE-2018-17456)
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
