CVE-2017-17458

mercurial: arbitrary command execution in mercurial repo with a git submodule

Published Dec 7, 2017 CVSS 3.0 · 9.8 Critical EPSS 6.3% KEV · Not listed
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.
