Linux kernel SMP page fault handler privilege escalation

linux-fault-handler-gain-privileges (18849)

High Risk

Description:

Linux kernel could allow a local attacker to gain elevated privileges on the system, caused by a race condition in the SMP page fault handler.

Consequences:

Gain Privileges

Remedy:

For Ubuntu Linux:
Upgrade to the latest linux-image package (2.6.8.1_2.6.8.1-16.10 or later), as listed in USN-60-0 January 14, 2005 for more information. See References.

For Red Hat Linux:
Refer to RHSA-2005:092-14, RHSA-2005:016-13, or RHSA-2005:017-14 for patch, upgrade, or suggested workaround information. See References.

For Debian GNU/Linux:
Refer to DSA-1070-1, DSA-1069-1, DSA-1067-1, or DSA-1082-1 for patch, upgrade, or suggested workaround information. See References.

For SUSE Linux:
Refer to SUSE-SA:2005:003 for patch, upgrade, or suggested workaround information. See References.

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