Description Diego Elio Pettenò (RETIRED) gentoo-dev 2006-12-04 00:33:20 UTC
Quoting from the site

Another vulnerability has been discovered in the CGI library (cgi.rb) that ships with Ruby which could be used by a malicious user to create a denial of service attack (DoS).

This vulnerability is open to the public as JVN#84798830.

Please note that the previous patch (<URL:>) does not fix this problem.


A specific HTTP request for any web application using cgi.rb causes CPU consumption on the machine on which the web application is running. Many such requests result in a denial of service.

Vulnerable versions

1.8 series
 1.8.5 and all prior versions 
Development version (1.9 series)
 All versions before 2006-12-04 


1.8 series
Please upgrade to 1.8.5-p2.
<URL:> (4519151 bytes, md5sum: a3517a224716f79b14196adda3e88057)
Please note that a package that corrects this weakness may already be available through your package management software.

I'll see to prepare an ebuild for 1.8.5-p2.
