Scientific Linux Security Update : libxml2 on SL6.x i386/x86_64 (20140519)

medium Nessus Plugin ID 74103

Language:

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.
