Users with Oracle Linux Premier Support can now use Ksplice to patch

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on EL 6 install these
updates.

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 action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* Information leak in mac80211 when transferring fragmented packet.

A flaw in the mac80211 stack could result in leaking 8 bytes of plain text
in the air. An attacker, physically in the range of the WiFi network, could
use this flaw to obtain sensitive informations.


* CVE-2014-8160: iptables rules by-pass when the protocol module is not loaded.

A flaw in the generic conntrack sub-system allows protocols that do not
have a protocol handler kernel module loaded to pass through the iptables
firewall even if explicitly denied by rule.


* CVE-2014-7825, CVE-2014-7826: Perf DoS and local privilege escalation.

A missing validation of syscall id range allows an attacker to trigger a
kernel panic, or leverage it into gaining root privileges if root was
doing perf tracing at that time.
