Ubuntu 18.04 LTS : linux, linux-aws, linux-azure, linux-gcp, linux-kvm, linux-oem, (USN-3732-1)

High Nessus Plugin ID 111579

Synopsis

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

Description

Juha-Matti Tilli discovered that the TCP implementation in the Linux
kernel performed algorithmically expensive operations in some
situations when handling incoming packets. A remote attacker could use
this to cause a denial of service.

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.
