Descriptions

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.

La función read_multipart en cgi.rb de Ruby anterior a 1.8.5-p2 no detecta adecuadamente los límites en contenido MIME multipart, lo cual permite a atacantes remotos provocar una denegación de servicio (bucle infinito) mediante una petición HTTP artesanal, un asunto diferente que CVE-2006-5467.
