Synopsis

The remote CentOS host is missing one or more security updates.

Description

An update for mercurial is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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.

Solution

Update the affected mercurial packages.
