CVE-2022-41903Public exploitNetwork attack vector

Code execution via commit-format padding integer overflow

Published Jan 17, 2023 · Updated Mar 10, 2025

Heap-based buffer overflow in Git allows remote attackers to execute code via crafted commit-format padding in git log or git archive. The format_and_pad_commit function narrows a size_t length to int and adds the overflowed value to a memcpy destination offset, enabling arbitrary heap writes. Exploitation requires a crafted formatting command locally or processing an untrusted repository through git archive, including an enabled git daemon service.
