Description:Summary:
The remote host is missing an update for the 'kernel'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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
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)

The CVE-2014-7841 issue was discovered by Liu Wei of Red Hat.
