--===============8573232852752685059== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="lzfPtAjrR1KYNfg0" Content-Disposition: inline --lzfPtAjrR1KYNfg0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-4346-1 April 29, 2020 linux, linux-aws, linux-kvm, linux-lts-xenial, linux-raspi2, linux-snapdragon vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS - Ubuntu 14.04 ESM Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-kvm: Linux kernel for cloud environments - linux-raspi2: Linux kernel for Raspberry Pi 2 - linux-snapdragon: Linux kernel for Snapdragon processors - linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty Details: It was discovered that the QLogic Fibre Channel driver in the Linux kernel did not properly check for error, leading to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-16233) It was discovered that the Intel Wi-Fi driver in the Linux kernel did not properly check for errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-16234) Tristan Madani discovered that the block I/O tracing implementation in the Linux kernel contained a race condition. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2019-19768) It was discovered that the virtual terminal implementation in the Linux kernel contained a race condition. A local attacker could possibly use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2020-8648) Jordy Zomer discovered that the floppy driver in the Linux kernel did not properly check for errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2020-9383) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: linux-image-4.4.0-1070-kvm 4.4.0-1070.77 linux-image-4.4.0-1106-aws 4.4.0-1106.117 linux-image-4.4.0-1132-raspi2 4.4.0-1132.141 linux-image-4.4.0-1136-snapdragon 4.4.0-1136.144 linux-image-4.4.0-178-generic 4.4.0-178.208 linux-image-4.4.0-178-generic-lpae 4.4.0-178.208 linux-image-4.4.0-178-lowlatency 4.4.0-178.208 linux-image-4.4.0-178-powerpc-e500mc 4.4.0-178.208 linux-image-4.4.0-178-powerpc-smp 4.4.0-178.208 linux-image-4.4.0-178-powerpc64-emb 4.4.0-178.208 linux-image-4.4.0-178-powerpc64-smp 4.4.0-178.208 linux-image-aws 4.4.0.1106.110 linux-image-generic 4.4.0.178.186 linux-image-generic-lpae 4.4.0.178.186 linux-image-kvm 4.4.0.1070.70 linux-image-lowlatency 4.4.0.178.186 linux-image-powerpc-e500mc 4.4.0.178.186 linux-image-powerpc-smp 4.4.0.178.186 linux-image-powerpc64-emb 4.4.0.178.186 linux-image-powerpc64-smp 4.4.0.178.186 linux-image-raspi2 4.4.0.1132.132 linux-image-snapdragon 4.4.0.1136.128 linux-image-virtual 4.4.0.178.186 Ubuntu 14.04 ESM: linux-image-4.4.0-1066-aws 4.4.0-1066.70 linux-image-4.4.0-178-generic 4.4.0-178.208~14.04.1 linux-image-4.4.0-178-lowlatency 4.4.0-178.208~14.04.1 linux-image-aws 4.4.0.1066.67 linux-image-generic-lts-xenial 4.4.0.178.157 linux-image-lowlatency-lts-xenial 4.4.0.178.157 linux-image-virtual-lts-xenial 4.4.0.178.157 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.
