New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

USN-3266-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.10.
This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.10 for Ubuntu 16.04 LTS.

Alexander Popov discovered that a race condition existed in the Stream Control Transmission Protocol (SCTP) implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash).

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 packages.
