Descriptions

multipart/parser.rb in Rack 1.3.x before 1.3.8 and 1.4.x before 1.4.3 allows remote attackers to cause a denial of service (memory consumption and out-of-memory error) via a long string in a Multipart HTTP packet.

multipart/parser.rb de Rack v1.3.x antes de v1.3.8 y v1.4.x antes de v1.4.3 permite a atacantes remotos causar una denegación de servicios (consumo de memoria y accesos fuera de rango) usando un long string en un paquete Multipart HTTP.

The update of librack-ruby in DSA-2783-1 also addressed CVE-2013-0183. The patch applied breaks rails applications like redmine (see Debian Bug #727187). Updated packages are available to address this problem.
