Synopsis
The remote Ubuntu host is missing one or more security-related patches.
Description
Jack Morgenstein reported a flaw in the page handling of the KVM (Kerenl Virtual Machine) subsystem in the Linux kernel. A guest OS user could exploit this flaw to cause a denial of service (host OS memory corruption) or possibly have other unspecified impact on the host OS. (CVE-2014-3601)
Jason Gunthorpe reported a flaw with SCTP authentication in the Linux kernel. A remote attacker could exploit this flaw to cause a denial of service (NULL pointer dereference and OOPS). (CVE-2014-5077)
Chris Evans reported an flaw in the Linux kernel's handling of iso9660 (compact disk filesystem) images. An attacker who can mount a custom iso9660 image either via a CD/DVD drive or a loopback mount could cause a denial of service (system crash or reboot). (CVE-2014-5471)
Chris Evans reported an flaw in the Linux kernel's handling of iso9660 (compact disk filesystem) images. An attacker who can mount a custom iso9660 image, with a self-referential CL entry, either via a CD/DVD drive or a loopback mount could cause a denial of service (unkillable mount process). (CVE-2014-5472).
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.
