Key facts

Description

Linux kernel before 2.6.15.3 down to 2.6.12, while constructing an ICMP response in icmp_send, does not properly handle when the ip_options_echo function in icmp.c fails, which allows remote attackers to cause a denial of service (crash) via vectors such as (1) record-route and (2) timestamp IP options with the needaddr bit set and a truncated value.
