DoS Vulnerability in CGI Library (CVE-2006-5467)
A 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). The problem is triggered by sending the library an HTTP request that uses multipart MIME encoding and has an invalid boundary specifier that begins with “-” instead of “–”. Once triggered it will exhaust all available memory resources effectively creating a DoS condition.
