--===============3456808478152078376== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="Y7xTucakfITjPcLV" Content-Disposition: inline --Y7xTucakfITjPcLV Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-3207-1 February 22, 2017 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 LTS Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: It was discovered that a use-after-free vulnerability existed in the block device layer of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2016-7910) Dmitry Vyukov discovered a use-after-free vulnerability in the sys_ioprio_get() function in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2016-7911) 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 14.04 LTS: linux-image-3.13.0-110-generic 3.13.0-110.157 linux-image-3.13.0-110-generic-lpae 3.13.0-110.157 linux-image-3.13.0-110-lowlatency 3.13.0-110.157 linux-image-3.13.0-110-powerpc-e500 3.13.0-110.157 linux-image-3.13.0-110-powerpc-e500mc 3.13.0-110.157 linux-image-3.13.0-110-powerpc-smp 3.13.0-110.157 linux-image-3.13.0-110-powerpc64-emb 3.13.0-110.157 linux-image-3.13.0-110-powerpc64-smp 3.13.0-110.157 linux-image-generic 3.13.0.110.118 linux-image-generic-lpae 3.13.0.110.118 linux-image-highbank 3.13.0.110.118 linux-image-lowlatency 3.13.0.110.118 linux-image-powerpc-e500 3.13.0.110.118 linux-image-powerpc-e500mc 3.13.0.110.118 linux-image-powerpc-smp 3.13.0.110.118 linux-image-powerpc64-emb 3.13.0.110.118 linux-image-powerpc64-smp 3.13.0.110.118 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.
