openSUSE Security Update : libxml2 (openSUSE-2016-583)

This script is Copyright (C) 2016 Tenable Network Security, Inc.

Synopsis :

The remote openSUSE host is missing a security update.

Description :

This update for libxml2 fixes two security issues :

- libxml2 limits the number of recursions an XML document
can contain so to protect against the 'Billion Laughs'
denial-of-service attack. Unfortunately, the underlying
counter was not incremented properly in all necessary
locations. Therefore, specially crafted XML documents
could exhaust all available stack space and crash the
XML parser without running into the recursion limit.
This vulnerability has been fixed. (bsc#975947)

- When running in recovery mode, certain invalid XML
documents would trigger an infinite recursion in libxml2
that ran until all stack space was exhausted. This
vulnerability could have been used to facilitate a
denial-of-sevice attack. (CVE-2016-3627, bsc#972335)

This update was imported from the SUSE:SLE-12:Update update project.
