iDEFENSE Security Advisory 12.03.2004 - Remote exploitation of an input validation vulnerability in Apple Computer Inc.'s Darwin Streaming Server allows attackers to cause a denial of service condition. The vulnerability specifically occurs due to insufficient sanity checking on arguments to DESCRIBE requests.

Apple Darwin Streaming Server DESCRIBE Null Byte Denial of Service

iDEFENSE Security Advisory 12.03.2004
December 03, 2004


Darwin Streaming Server is an open source version of Apple's QuickTime
Streaming Server technology that allows you to send streaming media to
clients across the Internet using the industry standard RTP and RTSP


Remote exploitation of an input validation vulnerability in Apple
Computer Inc.'s Darwin Streaming Server allows attackers to cause a
denial of service condition. The vulnerability specifically occurs due
to insufficient sanity checking on arguments to DESCRIBE requests. A
remote attacker can send a request for a location containing a null byte
to cause a denial of service condition resulting in the following

Program received signal SIGSEGV, Segmentation fault.

Successful exploitation allows any remote unauthenticated attacker to
crash the targeted server, thereby preventing legitimate users from
accessing streamed content.


iDEFENSE has confirmed the existence of this vulnerability in Darwin
Streaming Server 5.0.1. It is suspected that earlier versions are also
