Description

• A flaw was found in the way the Linux kernel's SCTP implementation
  validated INIT chunks when performing Address Configuration Change
  (ASCONF). A remote attacker could use this flaw to crash the system by
  sending a specially crafted SCTP packet to trigger a NULL pointer
  dereference on the system. (CVE-2014-7841, Important)

• An integer overflow flaw was found in the way the Linux kernel's Advanced
  Linux Sound Architecture (ALSA) implementation handled user controls.
  A local, privileged user could use this flaw to crash the system.
  (CVE-2014-4656, Moderate)
