Users with Oracle Linux Premier Support can now use Ksplice to patch
against this Security 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:

* Improved fix for CVE-2010-2962.

The original upstream fix for CVE-2010-2962 had an overflow bug in its
bounds checking.


* CVE-2012-0056: Privilege escalation in /proc/[pid]/mem writing.

It was found that permissions were not checked properly in the Linux
kernel when handling the /proc/[pid]/mem writing functionality.  A
local, unprivileged user could use this flaw to escalate their
privileges.
