Título:	CentOS Update for libxml2 CESA-2012:0324 centos6
Resumen:	The remote host is missing an update for the 'libxml2'; package(s) announced via the referenced advisory.
Descripción:	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 CentOS 6 Solution: Please install the updated packages. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
