Description

This security bulletin contains information about 1 security vulnerability.


1) Command injection (CVE-ID: CVE-2018-17456)

The vulnerability allows a remote attacker to execute arbitrary commands on the target system.

The weakness exists in the Git command line client, Git Desktop, and Atom due to command injection during processing of a recursive "git clone" of a superproject if a .gitmodules file has a URL field beginning with a '-' character.. A remote attacker can use a specially crafted.gitmodules file that contains an URL that starts with a dash. By using a dash, when Git clones a repository using the --recurse-submodules argument, the command will interpret the URL as an option that can be used to execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.
