CVE-2006-6303
First published: Wed Dec 06 2006(Updated: )
The read_multipart function in cgi.rb in Ruby before 1.8.5-p2 does not properly detect boundaries in MIME multipart content, which allows remote attackers to cause a denial of service (infinite loop) via crafted HTTP requests, a different issue than CVE-2006-5467.
