Test ID:1.3.6.1.4.1.25623.1.0.120420
Category:Amazon Linux Local Security Checks
Title:Amazon Linux: Security Advisory (ALAS-2014-449)
Summary:The remote host is missing an update for the 'ruby21' package(s) announced via the ALAS-2014-449 advisory.
Description:Summary:
The remote host is missing an update for the 'ruby21' package(s) announced via the ALAS-2014-449 advisory.

Vulnerability Insight:
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.

Affected Software/OS:
'ruby21' package(s) on Amazon Linux.

Solution:
Please install the updated package(s).

CVSS Score:
5.0
