Summary
linux-lts-xenial, linux-aws, linux-azure update
Details

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)
