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

The kernel-rt packages contain the Linux kernel, the core of any Linuxoperating system. A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handledsimultaneous connections between the same hosts. A remote attacker coulduse 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 useeither 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 usercontrol's state. A local, privileged user could use this flaw to leakkernel 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 lockingissues have been corrected, allowing the netconsole module to be re-enabledand functional on Realtime kernels. (BZ#1088923)Users are advised to upgrade to these updated packages, which upgrade thekernel-rt kernel to version kernel-rt-3.10.33-rt32.45 and correct theseissues. The system must be rebooted for this update to take effect.
