Linux kernel sys_perfmon() denial of service

kernel-sysperfmon-dos (29384) The risk level is classified as LowLow Risk

Description:

Linux kernel is vulnerable to a denial of service caused by improper handling of file descriptor reference counts by the sys_perfmon() function in the perfmon.c module. A remote attacker could exploit this vulnerability to cause a denial of service by consuming all available system resources.

Remedy:

Upgrade to the latest version of Linux Kernel (version 2.6.18 or later), available from the Linux Kernel Web site. See References.

For Red Hat Linux 4:
Refer to RHSA-2006:0689-15 for patch, upgrade, or suggested workaround information. See References.

Consequences:

Denial of Service
