The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Git is distributed revision control system. git log
can display commits in an arbitrary format using its --format
specifiers. This functionality is also exposed to git archive
via the export-subst
gitattribute. When processing the padding operators, there is a 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 git archive via the export-subst mechanism, which expands format specifiers inside of files within the repository during a git archive. This integer overflow can result in arbitrary heap writes, which may result in arbitrary code execution. The problem has been patched in the versions published on 2023-01-17, going back to v2.30.7. Users are advised to upgrade. Users who are unable to upgrade should disable git archive
in untrusted repositories. If you expose git archive via git daemon
, disable it by running git config --global daemon.uploadArch false
.
