DLA-1072-1 mercurial -- LTS security update
- Date Reported:
- 31 Aug 2017
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 871709, Bug 871710.
In Mitre's CVE dictionary: CVE-2017-1000115, CVE-2017-1000116.
- More information:
Two significant vulnerabilities were found in the Mercurial version control system which could lead to shell injection attacks and out-of-tree file overwrite.
Mercurial's symlink auditing was incomplete prior to 4.3, and could be abused to write to files outside the repository.
Mercurial was not sanitizing hostnames passed to ssh, allowing shell injection attacks on clients by specifying a hostname starting with -oProxyCommand. This vulnerability is similar to those in Git (CVE-2017-1000117) and Subversion (CVE-2017-9800).
For Debian 7
Wheezy, these problems have been fixed in version 2.2.2-4+deb7u5.
We recommend that you upgrade your mercurial packages.
