Scientific Linux Security Update : libxml2 on SL6.x, SL7.x i386/x86_64 (20141016)

medium Nessus Plugin ID 78646

Synopsis

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

Description

A denial of service flaw was found in libxml2, a library providing support to read, modify and write XML and HTML files. A remote attacker could provide a specially crafted XML file that, when processed by an application using libxml2, would lead to excessive CPU consumption (denial of service) based on excessive entity substitutions, even if entity substitution was disabled, which is the parser default behavior. (CVE-2014-3660)

The desktop must be restarted (log out, then log back in) for this update to take effect.

Solution

Update the affected packages.
