Ubuntu 16.04 LTS : linux-hwe vulnerability (USN-3292-2)

Medium Nessus Plugin ID 100254


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


USN-3292-1 fixed a vulnerability 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.

Jason Donenfeld discovered a heap overflow in the MACsec module in the Linux kernel. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.

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.


Update the affected packages.
