Description
In Mercurial before 4.4.1, it is possible that a specially malformed repository can cause Git subrepositories to run arbitrary code in the form of a .git/hooks/post-update script checked into the repository. Typical use of Mercurial prevents construction of such repositories, but they can be created programmatically.
CWEs
- CWE-78 · Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
