CVE-2022-41903: Integer overflow in `git archive`, `git log --format` leading to RCE in git

Noroxi assessment

Priority: Plan (action score 52/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 44.2% (FIRST EPSS); higher than 98.7% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: git (AlmaLinux:8) 2.31.1-3.el8_7; git-all (AlmaLinux:8) 2.31.1-3.el8_7; git-core (AlmaLinux:8) 2.31.1-3.el8_7.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Add it to your regular patch cycle. Upgrade to git (AlmaLinux:8) 2.31.1-3.el8_7; git-all (AlmaLinux:8) 2.31.1-3.el8_7; git-core (AlmaLinux:8) 2.31.1-3.el8_7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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`.
