Amazon Linux AMI : ruby19 (ALAS-2014-447)

medium Nessus Plugin ID 79296

Language:

Synopsis

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

Description

The upstream patch for CVE-2014-8080 introduced checks against the REXML.entity_expansion_text_limit, but did not add restrictions to limit the number of expansions performed, i.e. checks against the REXML::Document.entity_expansion_limit. As a consequence, even with the patch applied, a small XML document could cause REXML to use an excessive amount of CPU time. High memory usage can be achieved using larger inputs.

Solution

Run 'yum update ruby19' to update your system.
