Linux kernel icmp.c ip_options_echo() denial of service
| kernel-icmp-ipoptionsecho-dos (24575) |
Description:
Linux kernel versions 2.6.12 through 2.6.15.2 are vulnerable to a denial of service attack caused by improper handling of ICMP responses when the ip_iptions_echo() function in icmp.c fails. A remote attacker could exploit this vulnerability using a specially-crafted ICMP packet to cause the system to crash.

Remedy:
Upgrade to the latest stable version of Linux Kernel (2.6.15.3 or later), available from The Linux Kernel Archives. See References.
For Ubuntu Linux:
Refer to USN-250-1 for patch, upgrade, or suggested workaround information. See References.
For other distributions:
Contact your vendor for upgrade or patch information.
Consequences:
Denial of Service

- CVE-2006-0454: 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.
