From: ggilliss at netpublishing.com (Gregory A. Gilliss) Subject: Linux Kernel Fragment Reassembly DoS http://www.securityfocus.com/bid/7797 securityFocus is reporting that there exists a DoS associated with the handling of TCP packet reassembly in Linux (all versions vulnerable). Question - does that include broadcast addresses? If so, conceivably one could incapacitate all computers on a subnet with one fragment a la teardrop/Winnuke. G -- Gregory A.
