Amazon Linux AMI : libxml2 (ALAS-2012-52)

medium Nessus Plugin ID 69659

Language:

Synopsis

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

Description

It was found that the hashing routine used by libxml2 arrays was susceptible to predictable hash collisions. Sending a specially crafted message to an XML service could result in longer processing time, which could lead to a denial of service. To mitigate this issue, randomization has been added to the hashing function to reduce the chance of an attacker successfully causing intentional collisions.
(CVE-2012-0841)

Solution

Run 'yum update libxml2' to update your system.
