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 the way the Ruby POP module processed certain APOP
authentication requests. By sending certain responses when the Ruby APOP
module attempted to authenticate using APOP against a POP server, a remote
attacker could, potentially, acquire certain portions of a user's
authentication credentials. (CVE-2007-1558)

It was discovered that Ruby did not properly check the return value when
verifying X.509 certificates. This could, potentially, allow a remote
attacker to present an invalid X.509 certificate, and have Ruby treat it as
valid. (CVE-2009-0642)

A flaw was found in the way Ruby converted BigDecimal objects to Float
numbers. If an attacker were able to provide certain input for the
BigDecimal object converter, they could crash an application using this
class. (CVE-2009-1904)

All Ruby users should upgrade to these updated packages, which contain
backported patches to resolve these issues.

4. Solution:

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

This update is available via Red Hat Network.  Details on how to use
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259

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

241191 - CVE-2007-1558 fetchmail/mutt/evolution/...: APOP password disclosure vulnerability
486183 - CVE-2009-0642 ruby: Incorrect checks for validity of X.509 certificates
504958 - CVE-2009-1904 ruby: DoS vulnerability in BigDecimal
