Description Jan Lieskovsky 2009-09-09 15:57:18 UTC 
Common Vulnerabilities and Exposures assigned an identifier CVE-2009-3086 to
the following vulnerability:

A certain algorithm in Ruby on Rails 2.1.0 through 2.2.2, and 2.3.x
before 2.3.4, leaks information about the complexity of message-digest
signature verification in the cookie store, which might allow remote
attackers to forge a digest via multiple attempts.

Comment 1 Jan Lieskovsky 2009-09-09 16:02:01 UTC 
This issue affects the version of rubygem-actionpack, as shipped 
with Fedora release of 10 (and potentially also with 11 -- didn't check).

Please fix.
Comment 3 Jeroen van Meeuwen 2010-04-30 12:34:26 UTC 
I've submitted a build of 2.1.1 with the 2.2.x patch applied for review, I'll submit it to epel-5-updates stable or testing depending on today's feedback;

Comment 4 Vincent Danen 2011-06-14 19:58:26 UTC 
It doesn't look like rubygem-actionpack-2.1.1-6.el5 was ever submitted to EPEL5; when I look for the latest release version I see -5.el5.  Do you still intend to submit that fix?
Comment 5 Vincent Danen 2013-05-08 17:43:00 UTC 
Created rubygem-actionpack tracking bugs for this issue

Affects: epel-5 [bug 961066]
Comment 6 Vincent Danen 2013-05-08 17:45:09 UTC 
Tracking bug filed for EPEL5 so this can be followed up there; no need to keep this open when it's fixed everywhere else for the last three years.
