Tasha Drew reports:

Researchers investigating the Rails parameter parsing vulnerability discovered 
that the same or similar vulnerable code had made its way into multiple other 
libraries. If your application uses these libraries to process untrusted data, 
it may still be vulnerable even if you have upgraded Rails. Check your Gemfile 
and Gemfile.lock for vulnerable versions of the following libraries, and if you
are using one, update it immediately.

You can update each of these by using "bundle update <gem name>". 


Vulnerable: <= 0.3.1

Fixed: 0.3.2

Crack 0.3.2 has already been in the tree for several months, so we can mark that stable.

CVE-2013-1800 (
  The crack gem 0.3.1 and earlier for Ruby does not properly restrict casts of
  string values, which might allow remote attackers to conduct
  object-injection attacks and execute arbitrary code, or cause a denial of
  service (memory and CPU consumption) by leveraging Action Pack support for
  (1) YAML type conversion or (2) Symbol type conversion, a similar
  vulnerability to CVE-2013-0156.
