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

medium Nessus Plugin ID 79296


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


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.


Run 'yum update ruby19' to update your system.
