CVE-2017-9462
Published: 6 June 2017
In Mercurial before 4.1.3, "hg serve --stdio" allows remote authenticated users to launch the Python debugger, and consequently execute arbitrary code, by using --debugger as a repository name.
From the Ubuntu Security Team
It was discovered that Mercurial incorrectly handled repository names. An attacker could possibly use this issue to execute arbitrary code.
