Description

Mercurial Release Notes :

CVE-2017-1000115

Mercurial'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 is also present in Git (CVE-2017-1000117) and Subversion (CVE-2017-9800), so please patch those tools as well if you have them installed.
