- Date Reported:
- 28 Dec 2017
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2017-17458.
- More information:
A vulnerability was found in the Mercurial version control system which could lead to remote arbitrary code execution.
A specially malformed Mercurial repository could cause Git subrepositories to run arbitrary code in the form of a .git/hooks/post-update script checked into the parent repository. Typical use of Mercurial prevents construction of such repositories, but they can be created programmatically.
For Debian 7
Wheezy, these problems have been fixed in version 2.2.2-4+deb7u6.
We recommend that you upgrade your mercurial packages.
