(RHSA-2014:1083) Important: kernel-rt security and bug fix update

The kernel-rt packages contain the Linux kernel, the core of any Linux
operating system.

• A NULL pointer dereference flaw was found in the way the Linux kernel’s
  Stream Control Transmission Protocol (SCTP) implementation handled
  simultaneous connections between the same hosts. A remote attacker could
  use this flaw to crash the system. (CVE-2014-5077, Important)

• Multiple use-after-free flaws and an integer overflow flaw were found in
  the way the Linux kernel’s Advanced Linux Sound Architecture (ALSA)
  implementation handled user controls. A local, privileged user could use
  either of these flaws to crash the system. (CVE-2014-4653, CVE-2014-4654,
  CVE-2014-4655, CVE-2014-4656, Moderate)

• An information leak flaw was found in the way the Linux kernel’s Advanced
  Linux Sound Architecture (ALSA) implementation handled access of the user
  control’s state. A local, privileged user could use this flaw to leak
  kernel memory to user space. (CVE-2014-4652, Low)

This update also fixes the following bug:

• Prior to this update, the netconsole module was unavailable on MRG
  Realtime kernels due to locking issues that disabled it. These locking
  issues have been corrected, allowing the netconsole module to be re-enabled
  and functional on Realtime kernels. (BZ#1088923)

Users are advised to upgrade to these updated packages, which upgrade the
kernel-rt kernel to version kernel-rt-3.10.33-rt32.45 and correct these
issues. The system must be rebooted for this update to take effect.
