version 2.3.5-1.2+squeeze6.

For the testing distribution (wheezy), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in
version 2.3.14-6 of the ruby-activesupport-2.3 package.

The 3.2 version of rails as found in Debian wheezy and sid is not
affected by the problem.

We recommend that you upgrade your rails packages.";

crafted payload attackers can trick the backend into decoding a subset of
YAML.

The vulnerability has been addressed by removing the YAML backend and
adding the OkJson backend.";
