Amazon Linux AMI : libxml2 (ALAS-2014-444)

medium Nessus Plugin ID 79293

Synopsis

The remote Amazon Linux AMI host is missing a security update.

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)

Solution

Run 'yum update libxml2' to update your system.
