The _CFNetConnectionWillEnqueueRequests function in CFNetwork 129.19 on Apple Mac OS X 10.4 through 10.4.10 allows remote attackers to cause a denial of service (application crash) via a crafted HTTP 301 response, which results in a NULL pointer dereference.

The remote host is running a version of Mac OS X 10.4 that is older than version 10.4.11 or a version of Mac OS X 10.3 that does not have Security Update 2007-008 applied.  This update contains several security fixes for the following programs :

 - BIND
 - bzip2
 - CFFTP
 - CFNetwork
 - CoreFoundation
 - CoreText
 - Kerberos
 - Kernel

The remote host is running CFNetwork prior to 129.20.  CFNetwork is an API for Mac OS X users that allows an abstraction of common network protocols.  This version of CFNetwork is prone to a Denial of Service (DoS) flaw.  An attacker exploiting this flaw would be able to crash the application utilizing CFNetwork.
