(RHSA-2015:0115) Important: kernel security update

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

• A flaw was found in the way the Linux kernel’s SCTP implementation
  handled malformed or duplicate Address Configuration Change Chunks
  (ASCONF). A remote attacker could use either of these flaws to crash the
  system. (CVE-2014-3673, CVE-2014-3687, Important)

• A flaw was found in the way the Linux kernel’s SCTP implementation
  handled the association’s output queue. A remote attacker could send
  specially crafted packets that would cause the system to use an excessive
  amount of memory, leading to a denial of service. (CVE-2014-3688,
  Important)

The CVE-2014-3673 issue was discovered by Liu Wei of Red Hat.

All kernel users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. The system must be
rebooted for this update to take effect.
