[v3.2] ruby-activesupport4.2: Possible Denial of Service attack (CVE-2015-3227)
There is a possible denial of service attack in the XML processing in
Support. This vulnerability has been assigned the CVE identifier CVE-2015-3227.
Versions Affected: All.

Fixed Versions: 4.2.2, 4.1.11
Specially crafted XML documents can cause applications to raise a
`SystemStackError` and potentially cause a denial of service attack. This
only impacts applications using REXML or JDOM as their XML processor. Other
XML processors that Rails supports are not impacted.
All users running an affected release should either upgrade or use one of the work arounds immediately.
