Synopsis

The remote Red Hat host is missing a security update for ruby193-ruby.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2014:0011 advisory.

Ruby is an extensible, interpreted, object-oriented, scripting language.
It has features to process text files and to perform system management tasks.

A buffer overflow flaw was found in the way Ruby parsed floating point numbers from their text representation. If an application using Ruby accepted untrusted input strings and converted them to floating point numbers, an attacker able to provide such input could cause the application to crash or, possibly, execute arbitrary code with the privileges of the application. (CVE-2013-4164)

Users of Red Hat OpenStack 3.0 are advised to upgrade to these updated packages, which 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 ruby193-ruby package based on the guidance in RHSA-2014:0011.
