Name        : ruby
Product     : Fedora 15
Version     : 1.8.7.357
Release     : 1.fc15
URL         : http://www.ruby-lang.org/
Summary     : An interpreter of object-oriented scripting language
Description :
Ruby is the interpreted scripting language for quick and easy
object-oriented programming.  It has many features to process text
files and to do system management tasks (as in Perl).  It is simple,
straight-forward, and extensible.

--------------------------------------------------------------------------------
Update Information:

A security flaw was found on the previous ruby that with some series of strings which was specially crafted to intentionally collide their hash values with each other, rails applications may fall into denial of services when such strings are used in HTTP requests (CVE-2011-4815). This new ruby will fix this issue.
