Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

It was discovered that the keyring implementation in the Linux kernel
did not ensure a data structure was initialized before referencing it
after an error condition occurred. A local attacker could use this to
cause a denial of service (system crash). (CVE-2016-4470)

Kangjie Lu discovered an information leak in the netlink
implementation of the Linux kernel. A local attacker could use this to
obtain sensitive information from kernel memory. (CVE-2016-5243).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected linux-image-3.13-generic,
linux-image-3.13-generic-lpae and / or linux-image-3.13-lowlatency
packages.
