Description:	Summary: The remote host is missing an update for the 'linux-aws, linux-azure, linux-lts-xenial' package(s) announced via the USN-4041-2 advisory. Vulnerability Insight: USN-4041-1 provided updates for the Linux kernel in Ubuntu. This update provides the corresponding updates for the Linux kernel for Ubuntu 16.04 ESM. USN-4017-2 fixed vulnerabilities in the Linux kernel. Unfortunately, the update introduced a regression that interfered with networking applications that setup very low SO_SNDBUF values. This update fixes the problem. We apologize for the inconvenience. Jonathan Looney discovered that the Linux kernel could be coerced into segmenting responses into multiple TCP segments. A remote attacker could construct an ongoing sequence of requests to cause a denial of service. (CVE-2019-11479) Affected Software/OS: 'linux-aws, linux-azure, linux-lts-xenial' package(s) on Ubuntu 14.04. Solution: Please install the updated package(s).
