--===============3758241939777507592== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="gSSGYPGSs0dvYOj7" Content-Disposition: inline --gSSGYPGSs0dvYOj7 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-3189-1 February 03, 2017 linux, linux-raspi2, 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-raspi2: Linux kernel for Raspberry Pi 2 - linux-snapdragon: Linux kernel for Snapdragon Processors Details: Mikulas Patocka discovered that the asynchronous multibuffer cryptographic daemon (mcryptd) in the Linux kernel did not properly handle being invoked with incompatible algorithms. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-10147) Qidan He discovered that the ICMP implementation in the Linux kernel did not properly check the size of an ICMP header. A local attacker with CAP_NET_ADMIN could use this to expose sensitive information. (CVE-2016-8399) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: linux-image-4.4.0-1042-raspi2 4.4.0-1042.49 linux-image-4.4.0-1046-snapdragon 4.4.0-1046.50 linux-image-4.4.0-62-generic 4.4.0-62.83 linux-image-4.4.0-62-generic-lpae 4.4.0-62.83 linux-image-4.4.0-62-lowlatency 4.4.0-62.83 linux-image-4.4.0-62-powerpc-e500mc 4.4.0-62.83 linux-image-4.4.0-62-powerpc-smp 4.4.0-62.83 linux-image-4.4.0-62-powerpc64-emb 4.4.0-62.83 linux-image-4.4.0-62-powerpc64-smp 4.4.0-62.83 linux-image-generic 4.4.0.62.65 linux-image-generic-lpae 4.4.0.62.65 linux-image-lowlatency 4.4.0.62.65 linux-image-powerpc-e500mc 4.4.0.62.65 linux-image-powerpc-smp 4.4.0.62.65 linux-image-powerpc64-emb 4.4.0.62.65 linux-image-powerpc64-smp 4.4.0.62.65 linux-image-raspi2 4.4.0.1042.41 linux-image-snapdragon 4.4.0.1046.38 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.
