A flaw was found in Git, a distributed revision control system. This issue occurs due to an integer overflow in pretty.c::format_and_pad_commit()
, where a size_t
is stored improperly as an int
, and then added as an offset to a memcpy()
. This overflow can be triggered directly by a user running a command which invokes the commit formatting machinery (e.g., git log --format=...
). It may also be triggered indirectly through the git archive via the export-subst mechanism, which expands format specifiers inside files within the repository during a git archive. This integer overflow can result in arbitrary heap writes, which may allow arbitrary code execution.
