--===============2379542680731940846== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="XuV1QlJbYrcVoo+x" Content-Disposition: inline --XuV1QlJbYrcVoo+x Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-2840-1 December 17, 2015 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 LTS Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: Dmitry Vyukov discovered that the Linux kernel's keyring handler attempted to garbage collect incompletely instantiated keys. A local unprivileged attacker could use this to cause a denial of service (system crash). (CVE-2015-7872) Jan Beulich discovered that the KVM svm hypervisor implementation in the Linux kernel did not properly catch Debug exceptions on AMD processors. An attacker in a guest virtual machine could use this to cause a denial of service (system crash) in the host OS. (CVE-2015-8104) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 LTS: linux-image-3.2.0-96-generic 3.2.0-96.136 linux-image-3.2.0-96-generic-pae 3.2.0-96.136 linux-image-3.2.0-96-highbank 3.2.0-96.136 linux-image-3.2.0-96-omap 3.2.0-96.136 linux-image-3.2.0-96-powerpc-smp 3.2.0-96.136 linux-image-3.2.0-96-powerpc64-smp 3.2.0-96.136 linux-image-3.2.0-96-virtual 3.2.0-96.136 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. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
