3. Description:

 

The libxml2 library is a development toolbox providing the implementation

of various XML standards.

 

It was discovered that libxml2 loaded external parameter entities even when

entity substitution was disabled. A remote attacker able to provide a

specially crafted XML file to an application linked against libxml2 could

use this flaw to conduct XML External Entity (XXE) attacks, possibly

resulting in a denial of service or an information leak on the system.

(CVE-2014-0191)

 

The CVE-2014-0191 issue was discovered by Daniel P. Berrange of Red Hat.

 

All libxml2 users 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.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.
