Two vulnerabilities were discovered in Ruby on Rails, a Ruby framework
for web application development.
- CVE-2013-0276
The blacklist provided by the attr_protected method could be
bypassed with crafted requests, having an application-specific
impact.
- CVE-2013-0277
In some applications, the +serialize+ helper in ActiveRecord
could be tricked into deserializing arbitrary YAML data,
possibly leading to remote code execution.
For the stable distribution (squeeze), these problems have been fixed
in version 2.3.5-1.2+squeeze7.
We recommend that you upgrade your rails packages.
