Description Josh Bressers 2004-08-16 20:19:36 UTC 
From the Debian DSA

Andres Salomon no ticed a problem in the CGI session management of
Ruby, an object-oriented scripting language.  CGI::Session's FileStore
(and presumably PStore, but not in Debian woody) implementations store
session information insecurely.  They simply create files, ignoring
permission issues.  This can lead an attacker who has also shell
access to the webserver to take over a session.

This issue was reported to the Debian bug system
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=260779

This issue should also affect RHEL2.1

Fedora Core is being handled by bug 130063

I can verify your new rpms fix the problem.  I'll attach my little
