Fedora 16 : ruby-1.8.7.357-1.fc16 (2011-17542)

Synopsis :

The remote Fedora host is missing a security update.

Description :

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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
