Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated ruby packages that fix one security issue are now available
for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

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

A flaw was found in Ruby's SSL client's hostname identity check when
handling certificates that contain hostnames with NULL bytes. An
attacker could potentially exploit this flaw to conduct
man-in-the-middle attacks to spoof SSL servers. Note that to exploit
this issue, an attacker would need to obtain a carefully-crafted
certificate signed by an authority that the client trusts.

All users of Ruby are advised to upgrade to these updated packages,
which contain backported patches to resolve this issue.
