Discussion

Multiple Linux Vendor Zero-Length Fragment Vulnerability

Linux kernel versions 2.1.89 to 2.2.3 are vulnerable to a denial of service attack caused when a 0-length IP fragment is received, if it is the first fragment in the list. Several thousands 0-length packets must be sent in order for this to initiate a denial of service against the target.
