New! Plugin Severity Now Using CVSS v3

Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
A stack overflow was discovered in the the microcode loader for the intel x86 platform. A local attacker could exploit this flaw to cause a denial of service (kernel crash) or to potentially execute code with kernel privileges. (CVE-2015-2666)It was discovered that the Linux kernel's IPv6 networking stack has a flaw that allows using route advertisement (RA) messages to set the 'hop_limit' to values that are too low. An unprivileged attacker on a local network could exploit this flaw to cause a denial of service (IPv6 messages dropped). (CVE-2015-2922).
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.See Also
