CentOS Errata and Security Advisory CESA-2017:2004
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):
It was found that the git-prompt.sh script shipped with git failed to correctly handle branch names containing special characters. A specially crafted git repository could use this flaw to execute arbitrary commands if a user working with the repository configured their shell to include repository information in the prompt. (CVE-2014-9938)
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)
