Red Hat Security Advisory 2013-1090-01
Posted Jul 17, 2013
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-1090-01 - 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.

3. Description:

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. (CVE-2013-4073)

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

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/site/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):
