CVE-2016-3068
Blake Burkhart discovered that Mercurial allows URLs for Git subrepositories that could result in arbitrary code execution on clone.
CVE-2016-3069
Blake Burkhart discovered that Mercurial allows arbitrary code execution when converting Git repositories with specially crafted names.
CVE-2016-3630
It was discovered that Mercurial does not properly perform bounds-checking in its binary delta decoder, which may be exploitable for remote code execution via clone, push or pull.
For the oldstable distribution (wheezy), these problems have been fixed in version 2.2.2-4+deb7u2.
For the stable distribution (jessie), these problems have been fixed in version 3.1.2-2+deb8u2.
For the unstable distribution (sid), these problems have been fixed in version 3.7.3-1.
We recommend that you upgrade your mercurial packages.");
