CVE-2017-17458 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:18.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream mercurial package and not the mercurial package as distributed by Ubuntu.
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.
