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:

* CVE-2012-2745: Denial-of-service in kernel key management.

A potential double-free of the replacement session keyring on fork()
could result in a denial-of-service by a local, unprivileged user.


* CVE-2011-1083: Algorithmic denial of service in epoll.

A flaw was found in the way the Linux kernel's Event Poll (epoll)
subsystem handled large, nested epoll structures. A local,
unprivileged user could use this flaw to cause a denial of service.
