Fixed In Version: mercurial 3.8
Doc Type: Bug Fix
Doc Text:
It was discovered that the Mercurial convert extension invoked Git in a way that could cause Git to interpret local repository name as remote repository URL. A Git repository with a specially crafted name could cause Mercurial to execute arbitrary code when the Git repository was converted to a Mercurial repository.

Description Andrej Nemec 2016-05-04 08:08:37 EDT 
A possible arbitrary code execution when converting Git repos was found in Mercirual.  Mercurial prior to 3.8 allowed arbitrary code execution when using the convert extension on Git repos with hostile names. This could affect automated code conversion services that allow arbitrary repository names. This is a further side-effect of Git CVE-2015-7545.
