Type Values Removed Values Added
Description A flaw was found in git. An authenticated remote attacker can cause a Denial of Service (DoS) by corrupting stack memory during merge operations. This issue occurs when git attempts to remove more than two GPG (GNU Privacy Guard) signatures from commit messages. By submitting a specially crafted commit containing multiple signatures, an attacker can crash the git process.
