3. Description:

Mercurial is a fast, lightweight source control management system designed
for efficient handling of very large distributed projects.

Security Fix(es):

* It was discovered that Mercurial failed to properly check Git
sub-repository URLs. A Mercurial repository that includes a Git
sub-repository with a specially crafted URL could cause Mercurial to
execute arbitrary code. (CVE-2016-3068)

* It was discovered that the Mercurial convert extension failed to sanitize
special characters in Git repository names. 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. (CVE-2016-3069)

Red Hat would like to thank Blake Burkhart for reporting these issues.
