--===============0040467956331705812== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="pcpnhe4g5wbcs76p" Content-Disposition: inline --pcpnhe4g5wbcs76p Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-3405-1 August 28, 2017 linux, linux-aws, linux-gke, 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 Linux kernel. Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-gke: Linux kernel for Google Container Engine (GKE) systems - linux-raspi2: Linux kernel for Raspberry Pi 2 - linux-snapdragon: Linux kernel for Snapdragon processors Details: It was discovered that a use-after-free vulnerability existed in the POSIX message queue implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-11176) Huang Weller discovered that the ext4 filesystem implementation in the Linux kernel mishandled a needs-flushing-before-commit list. A local attacker could use this to expose sensitive information. (CVE-2017-7495) It was discovered that a buffer overflow existed in the Broadcom FullMAC WLAN driver in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7541) It was discovered that the Linux kernel did not honor the UEFI secure boot mode when performing a kexec operation. A local attacker could use this to bypass secure boot restrictions. (CVE-2015-7837) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: linux-image-4.4.0-1028-gke 4.4.0-1028.28 linux-image-4.4.0-1032-aws 4.4.0-1032.41 linux-image-4.4.0-1071-raspi2 4.4.0-1071.79 linux-image-4.4.0-1073-snapdragon 4.4.0-1073.78 linux-image-4.4.0-93-generic 4.4.0-93.116 linux-image-4.4.0-93-generic-lpae 4.4.0-93.116 linux-image-4.4.0-93-lowlatency 4.4.0-93.116 linux-image-4.4.0-93-powerpc-e500mc 4.4.0-93.116 linux-image-4.4.0-93-powerpc-smp 4.4.0-93.116 linux-image-4.4.0-93-powerpc64-emb 4.4.0-93.116 linux-image-4.4.0-93-powerpc64-smp 4.4.0-93.116 linux-image-aws 4.4.0.1032.34 linux-image-generic 4.4.0.93.98 linux-image-generic-lpae 4.4.0.93.98 linux-image-gke 4.4.0.1028.29 linux-image-lowlatency 4.4.0.93.98 linux-image-powerpc-smp 4.4.0.93.98 linux-image-powerpc64-emb 4.4.0.93.98 linux-image-powerpc64-smp 4.4.0.93.98 linux-image-raspi2 4.4.0.1071.71 linux-image-snapdragon 4.4.0.1073.65 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.
