The support and utility classes used by the Rails 3.2 framework allow remote attackers to cause a denial of service (SystemStackError) via a large XML document depth.

For Debian 7 β€˜Wheezy’, these problems have been fixed in version 3.2.6-6+deb7u2.

Additionally this upload adds β€˜active_support/security_utils’ that will be used by ruby-actionpack-3.2 to address CVE-2015-7576.

We recommend that you upgrade your ruby-activesupport-3.2 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
