rails - several

Two vulnerabilities were discovered in Ruby on Rails, a web
application framework. The Common Vulnerabilities and Exposures
project identifies the following problems:

• CVE-2009-3086

The cookie store may be vulnerable to a timing attack,
potentially allowing remote attackers to forge message
digests.

• CVE-2009-4214

A cross-site scripting vulnerability in the strip_tags
function allows remote user-assisted attackers to inject
arbitrary web script.

For the oldstable distribution (lenny), these problems have been fixed
in version 2.1.0-7+lenny0.2.

For the other distributions, these problems have been fixed in version
2.2.3-2.

We recommend that you upgrade your rails packages.
