--===============8726768441388289132== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="LQFJYnjHKDAbJRTQ" Content-Disposition: inline --LQFJYnjHKDAbJRTQ Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-2978-1 May 16, 2016 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 15.10 Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: David Matlack discovered that the Kernel-based Virtual Machine (KVM) implementation in the Linux kernel did not properly restrict variable Memory Type Range Registers (MTRR) in KVM guests. A privileged user in a guest VM could use this to cause a denial of service (system crash) in the host, expose sensitive information from the host, or possibly gain administrative privileges in the host. (CVE-2016-3713) Philip Pettersson discovered that the Linux kernel's ASN.1 DER decoder did not properly process certificate files with tags of indefinite length. A local unprivileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2016-0758) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 15.10: linux-image-4.2.0-36-generic 4.2.0-36.42 linux-image-4.2.0-36-generic-lpae 4.2.0-36.42 linux-image-4.2.0-36-lowlatency 4.2.0-36.42 linux-image-4.2.0-36-powerpc-e500mc 4.2.0-36.42 linux-image-4.2.0-36-powerpc-smp 4.2.0-36.42 linux-image-4.2.0-36-powerpc64-emb 4.2.0-36.42 linux-image-4.2.0-36-powerpc64-smp 4.2.0-36.42 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.
