TITLE:
Red Hat update for kernel

SECUNIA ADVISORY ID:
SA24300

VERIFY ADVISORY:
http://secunia.com/advisories/24300/

CRITICAL:
Not critical

IMPACT:
DoS

WHERE:
Local system

OPERATING SYSTEM:
RedHat Enterprise Linux WS 4
http://secunia.com/product/4670/
RedHat Enterprise Linux ES 4
http://secunia.com/product/4668/
RedHat Enterprise Linux AS 4
http://secunia.com/product/4669/

DESCRIPTION:
Red Hat has issued an update for the kernel. This fixes some
vulnerabilities, which can be exploited by malicious, local users to
cause a DoS (Denial of Service).

1) An error within the auditing subsystem can be exploited to cause a
kernel panic. Successful exploitation requires that the attacker
previously created a watch for a file.

2) A NULL pointer dereference error within the "key_alloc_serial()"
function can be exploited to crash the kernel.

SOLUTION:
Updated packages are available from Red Hat Network.
