Users with Oracle Linux Premier Support can now use Ksplice to patch
against this Bug Fix Advisory.

We recommend that all users of  Oracle Linux 5 install these updates.

Users of Ksplice Uptrack can install these updates by running :

# /usr/sbin/uptrack-upgrade -y
On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any additional action.

Description of changes:

* Improve performance of kernel core dump.

Accesses to /proc/vmcore have been tuned to improve the performance of
obtaining a kernel core file.


* CVE-2012-1601: Denial of service in KVM VCPU creation.

Inconsistent state in the creation of KVM virtual CPU's could
lead to NULL pointer dereferences.  A unprivileged local user
could use this flaw to crash the system.


* NULL pointer dereference in SCSI subsystem.

A NULL pointer dereference in the SCSI subsystem could result in a
kernel panic.
