RHEL 3 : cyrus-sasl (RHSA-2007:0878)

Synopsis :

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

Description :

Updated cyrus-sasl packages that correct a security issue are now
available for Red Hat Enterprise Linux 3.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

The cyrus-sasl package contains the Cyrus implementation of SASL. SASL
is the Simple Authentication and Security Layer, a method for adding
authentication support to connection-based protocols.

A bug was found in cyrus-sasl's DIGEST-MD5 authentication mechanism.
As part of the DIGEST-MD5 authentication exchange, the client is
expected to send a specific set of information to the server. If one
of these items (the 'realm') was not sent or was malformed, it was
possible for a remote unauthenticated attacker to cause a denial of
service (segmentation fault) on the server. (CVE-2006-1721)

Users of cyrus-sasl should upgrade to these updated packages, which
contain a backported patch to correct this issue.
