Package : mercurial
Version : 2.2.2-4+deb7u5
CVE ID : CVE-2017-1000115 CVE-2017-1000116
Debian Bug : 871709 871710

Two significant vulnerabilities were found in the Mercurial version
control system which could lead to shell injection attacks and
out-of-tree file overwrite.

CVE-2017-1000115

Mercurial&#x27;s symlink auditing was incomplete prior to 4.3, and
could be abused to write to files outside the repository.

CVE-2017-1000116

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.
