--===============4366935012488558234== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="veXX9dWIonWZEC6h" Content-Disposition: inline --veXX9dWIonWZEC6h Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-3208-1 February 22, 2017 linux, linux-snapdragon vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel - linux-snapdragon: Linux kernel for Snapdragon Processors Details: It was discovered that the generic SCSI block layer in the Linux kernel did not properly restrict write operations in certain situations. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2016-10088) CAI Qian discovered that the sysctl implementation in the Linux kernel did not properly perform reference counting in some situations. An unprivileged attacker could use this to cause a denial of service (system hang). (CVE-2016-9191) Jim Mattson discovered that the KVM implementation in the Linux kernel mismanages the #BP and #OF exceptions. A local attacker in a guest virtual machine could use this to cause a denial of service (guest OS crash). (CVE-2016-9588) Andy Lutomirski and Willy Tarreau discovered that the KVM implementation in the Linux kernel did not properly emulate instructions on the SS segment register. A local attacker in a guest virtual machine could use this to cause a denial of service (guest OS crash) or possibly gain administrative privileges in the guest OS. (CVE-2017-2583) Dmitry Vyukov discovered that the KVM implementation in the Linux kernel improperly emulated certain instructions. A local attacker could use this to obtain sensitive information (kernel memory). (CVE-2017-2584) It was discovered that the KLSI KL5KUSB105 serial-to-USB device driver in the Linux kernel did not properly initialize memory related to logging. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-5549) Andrey Konovalov discovered a use-after-free vulnerability in the DCCP implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2017-6074) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: linux-image-4.4.0-1048-snapdragon 4.4.0-1048.52 linux-image-4.4.0-64-generic 4.4.0-64.85 linux-image-4.4.0-64-generic-lpae 4.4.0-64.85 linux-image-4.4.0-64-lowlatency 4.4.0-64.85 linux-image-4.4.0-64-powerpc-e500mc 4.4.0-64.85 linux-image-4.4.0-64-powerpc-smp 4.4.0-64.85 linux-image-4.4.0-64-powerpc64-emb 4.4.0-64.85 linux-image-4.4.0-64-powerpc64-smp 4.4.0-64.85 linux-image-generic 4.4.0.64.68 linux-image-generic-lpae 4.4.0.64.68 linux-image-lowlatency 4.4.0.64.68 linux-image-powerpc-e500mc 4.4.0.64.68 linux-image-powerpc-smp 4.4.0.64.68 linux-image-powerpc64-emb 4.4.0.64.68 linux-image-powerpc64-smp 4.4.0.64.68 linux-image-snapdragon 4.4.0.1048.40 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.
