Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 ESM Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty 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) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 ESM: After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
