Title:RedHat Security Advisory RHSA-2012:0324
The remote host is missing updates announced in
advisory RHSA-2012:0324.

The libxml2 library is a development toolbox providing the implementation
of various XML standards.

It was found that the hashing routine used by libxml2 arrays was
susceptible to predictable hash collisions. Sending a specially-crafted
message to an XML service could result in longer processing time, which
could lead to a denial of service. To mitigate this issue, randomization
has been added to the hashing function to reduce the chance of an attacker
successfully causing intentional collisions. (CVE-2012-0841)

All users of libxml2 are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. The desktop must
be restarted (log out, then log back in) for this update to take effect.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date

Risk factor : Medium
