Remedy:

Upgrade to the latest stable version of Linux kernel (2.6.15.5 or later), available from The Linux Kernel Archives. See References.

For Red Hat Linux 4:
Refer to RHSA-2006:0493-6 for patch, upgrade, or suggested workaround information. See References.

For Red Hat Linux 3:
Refer to RHSA-2006:0437-22 for patch, upgrade, or suggested workaround information. See References.

For Debian GNU/Linux:
Refer to DSA-1097-1 and DSA-1103-1 for patch, upgrade, or suggested workaround information. See References.

For Ubuntu Linux:
Refer to USN-263-1 for patch, upgrade, or suggested workaround information. See References.

For SUSE Linux:
Refer to SUSE-SA:2006:028 for patch, upgrade, or suggested workaround information. See References.

For other distributions:
Contact your vendor for upgrade or patch information.

Consequences:

Denial of Service
