Amazon Linux AMI : libxml2 (ALAS-2012-143)

medium Nessus Plugin ID 69633

Language:

Synopsis

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

Description

A heap-based buffer underflow flaw was found in the way libxml2 decoded certain entities. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2012-5134)

Solution

Run 'yum update libxml2' to update your system.
