CVE-2012-0841 Open this link in a new tabHow to fix?
Upgrade Centos:6 libxml2 to version 0:2.7.6-4.el6_2.4 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libxml2 package and not the libxml2 package as distributed by Centos.
See How to fix? for Centos:6 relevant fixed versions and status.
libxml2 before 2.8.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted XML data.
