CWE-78

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.

Affected configurations

• mercurial mercurial (< 4.4.1) • debian debian linux 7.0 • debian debian linux 8.0
