Scientific Linux Security Update : libxml2 on SL6.x i386/x86_64
Medium Nessus Plugin ID 74103
Synopsis
The remote Scientific Linux host is missing one or more security updates.
Description
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)
An out-of-bounds read flaw was found in the way libxml2 detected the end of an XML file. A remote attacker could provide a specially crafted XML file that, when processed by an application linked against libxml2, could cause the application to crash. (CVE-2013-2877)
The desktop must be restarted (log out, then log back in) for this update to take effect.
Solution
Update the affected packages.
