Test ID:1.3.6.1.4.1.25623.1.0.870569
Category:Red Hat Local Security Checks
Title:RedHat Update for libxml2 RHSA-2012:0324-01
Summary:The remote host is missing an update for the 'libxml2'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'libxml2'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.

Affected Software/OS:
libxml2 on Red Hat Enterprise Linux (v. 5 server)

Solution:
Please Install the Updated Packages.
