Amazon Linux AMI : libxml2 (ALAS-2014-341)

medium Nessus Plugin ID 78284

Synopsis

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

Description

It was discovered that libxml2, a library providing support to read, modify and write XML files, incorrectly performs entity substituton in the doctype prolog, even if the application using libxml2 disabled any entity substitution. A remote attacker could provide a specially crafted XML file that, when processed, would lead to the exhaustion of CPU and memory resources or file descriptors.

Solution

Run 'yum update libxml2' to update your system.
