Linux kernel TSS gain privilege
| linux-tss-gain-privilege (18346) |  High Risk |
Description:
Linux kernel versions prior to 2.4.23 running on AMD's AMD64 and Intel's EM64T could allow a local attacker to gain elevated privileges. There is a vulnerability in the setting of TSS limits. A local attacker could exploit this vulnerability to cause the system to crash or gain elevated privileges.
Consequences:
Gain Privileges
Remedy:
Upgrade to the latest version (2.4.23 or later), available from the Linux Kernel Web site. See References.
For Red Hat Linux:
Upgrade to the latest kernel package, as listed below. Refer to RHSA-2004:549-10 for more information. See References.
Red Hat Enterprise Linux Desktop and ES, AS, WS (v. 3): 2.4.21-20.0.1.EL or later
