Description :

The Ruby developers discovered a potential Denial of Service
vulnerability in the CGI module (cgi.rb). Specially crafted CGI
requests could cause an infinite loop in the server process.
Repetitive attacks could use most of the available processor
resources, exhaust the number of permited parallel connections in web
servers, or cause similar effects which render the service
unavailable.

There is no possibility of privilege escalation or data loss.

Solution :

Upgrade to :
- irb1.8-1.8.1+1.8.2pre2-3ubuntu0.1 (Ubuntu 4.10)
