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.
