Description

A flaw was found in the Linux kernel's netfilter ARP (Address Resolution Protocol) tables. When processing IPv4-over-IEEE1394 ARP packets on IEEE1394 interfaces, the kernel incorrectly parses the ARP payload. This can lead to incorrect filtering decisions by arptables, where packets that should be accepted may be dropped, and vice versa, resulting in a Denial of Service (DoS). Furthermore, attempts to mangle target hardware or IP addresses in IEEE1394 ARP packets can cause packet corruption, also leading to a Denial of Service.
