--===============7237764545584446480== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="0OWHXb1mYLuhj1Ox" Content-Disposition: inline --0OWHXb1mYLuhj1Ox Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-3221-1 March 08, 2017 linux, linux-raspi2 vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.10 Summary: The system could be made to crash or run programs as an administrator. Software Description: - linux: Linux kernel - linux-raspi2: Linux kernel for Raspberry Pi 2 Details: Alexander Popov discovered that the N_HDLC line discipline implementation in the Linux kernel contained a double-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.10: linux-image-4.8.0-1028-raspi2 4.8.0-1028.31 linux-image-4.8.0-41-generic 4.8.0-41.44 linux-image-4.8.0-41-generic-lpae 4.8.0-41.44 linux-image-4.8.0-41-lowlatency 4.8.0-41.44 linux-image-4.8.0-41-powerpc-e500mc 4.8.0-41.44 linux-image-4.8.0-41-powerpc-smp 4.8.0-41.44 linux-image-4.8.0-41-powerpc64-emb 4.8.0-41.44 linux-image-generic 4.8.0.41.52 linux-image-generic-lpae 4.8.0.41.52 linux-image-lowlatency 4.8.0.41.52 linux-image-powerpc-e500mc 4.8.0.41.52 linux-image-powerpc-smp 4.8.0.41.52 linux-image-powerpc64-emb 4.8.0.41.52 linux-image-raspi2 4.8.0.1028.31 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.
