--===============4444376376359024862== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="Tu8ztk+XgTAiG9Id" Content-Disposition: inline --Tu8ztk+XgTAiG9Id Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-4095-2 August 13, 2019 linux-lts-xenial, linux-aws vulnerabilities ========================================================================== 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-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty Details: USN-4095-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 ESM. Eli Biham and Lior Neumann discovered that the Bluetooth implementation in the Linux kernel did not properly validate elliptic curve parameters during Diffie-Hellman key exchange in some situations. An attacker could use this to expose sensitive information. (CVE-2018-5383) It was discovered that a heap buffer overflow existed in the Marvell Wireless LAN device driver for the Linux kernel. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-10126) Andrei Vlad Lutas and Dan Lutas discovered that some x86 processors incorrectly handle SWAPGS instructions during speculative execution. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2019-1125) It was discovered that the ext4 file system implementation in the Linux kernel did not properly zero out memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2019-11833) It was discovered that the PowerPC dlpar implementation in the Linux kernel did not properly check for allocation errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-12614) It was discovered that the Linux kernel on ARM processors allowed a tracing process to modify a syscall after a seccomp decision had been made on that syscall. A local attacker could possibly use this to bypass seccomp restrictions. (CVE-2019-2054) It was discovered that the Marvell Wireless LAN device driver in the Linux kernel did not properly validate the BSS descriptor. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-3846) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 ESM: linux-image-4.4.0-1050-aws 4.4.0-1050.54 linux-image-4.4.0-159-generic 4.4.0-159.187~14.04.1 linux-image-4.4.0-159-generic-lpae 4.4.0-159.187~14.04.1 linux-image-4.4.0-159-lowlatency 4.4.0-159.187~14.04.1 linux-image-4.4.0-159-powerpc-e500mc 4.4.0-159.187~14.04.1 linux-image-4.4.0-159-powerpc-smp 4.4.0-159.187~14.04.1 linux-image-4.4.0-159-powerpc64-emb 4.4.0-159.187~14.04.1 linux-image-4.4.0-159-powerpc64-smp 4.4.0-159.187~14.04.1 linux-image-aws 4.4.0.1050.51 linux-image-generic-lpae-lts-xenial 4.4.0.159.140 linux-image-generic-lts-xenial 4.4.0.159.140 linux-image-lowlatency-lts-xenial 4.4.0.159.140 linux-image-powerpc-e500mc-lts-xenial 4.4.0.159.140 linux-image-powerpc-smp-lts-xenial 4.4.0.159.140 linux-image-powerpc64-emb-lts-xenial 4.4.0.159.140 linux-image-powerpc64-smp-lts-xenial 4.4.0.159.140 linux-image-virtual-lts-xenial 4.4.0.159.140 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.
