Details

Git is an open source, scalable, distributed revision control system. git shell is a restricted login shell that can be used to implement Git's push/pull functionality via SSH. In versions prior to 2.30.6, 2.31.5, 2.32.4, 2.33.5, 2.34.5, 2.35.5, 2.36.3, and 2.37.4, the function that splits the command arguments into an array improperly uses an int to represent the number of entries in the array, allowing a malicious actor to intentionally overflow the return value, leading to arbitrary heap writes. Because the resulting array is then passed to execv(), it is possible to leverage this attack to gain remote code execution on a victim machine. Note that a victim must first allow access to git shell as a login shell in order to be vulnerable to this attack. This problem is patched in versions 2.30.6, 2.31.5, 2.32.4, 2.33.5, 2.34.5, 2.35.5, 2.36.3, and 2.37.4 and users are advised to upgrade to the latest version. Disabling git shell access via remote logins is a viable short-term workaround.
