IMPACT:
Exposure of sensitive information, DoS

WHERE:
Local system

OPERATING SYSTEM:

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) or to disclose potentially sensitive
information.

1) A race condition error in the "ptrace()" implementation can be
exploited to crash the kernel. 

2) An unspecified error in the 32-bit and 64-bit emulation can be
exploited to disclose potentially sensitive data via a specially
crafted binary.

3) An error while copying memory from userspace can be exploited to
disclose potentially sensitive information.

For more information see vulnerability #2 in:
SA23073

SOLUTION:
Updated packages are available via Red Hat Network.
