Scientific Linux Security Update : libxml2 on SL5.x, SL6.x i386/x86_64 (20120221)

medium Nessus Plugin ID 61268

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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.

Solution

Update the affected packages.
