RHEL 6 : rubygems (RHSA-2014:0207)

high Nessus Plugin ID 119345

Synopsis

The remote Red Hat host is missing a security update for rubygems.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2014:0207 advisory.

RubyGems is the Ruby standard for publishing and managing third-party libraries.

It was discovered that the rubygems API validated version strings using an unsafe regular expression. An application making use of this API to process a version string from an untrusted source could be vulnerable to a denial of service attack through CPU exhaustion. (CVE-2013-4287)

Red Hat would like to thank Rubygems upstream for reporting this issue.
Upstream acknowledges Damir Sharipov as the original reporter.

All users of Red Hat OpenShift Enterprise 2.0.2 are advised to upgrade to this updated package, which contains a backported patch to correct this issue.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL rubygems package based on the guidance in RHSA-2014:0207.
