Ruby is an interpreted scripting language for object-oriented programming.

A bug was found in the way ruby handles eval statements. It is possible for a malicious script to call eval in such a way that can allow the bypass of certain safe-level restrictions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-2337 to this issue.

Users of Ruby should update to these erratum packages, which contain a backported patch and are not vulnerable to this issue.
