CentOS Errata and Security Advisory CESA-2017:2484

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)
