--===============6379871660759136527== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="huu3jwlh2qxowro2" Content-Disposition: inline --huu3jwlh2qxowro2 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-3404-2 August 28, 2017 linux-hwe vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS Summary: The system could be made to crash under certain conditions. Software Description: - linux-hwe: Linux hardware enablement (HWE) kernel Details: USN-3404-1 fixed a vulnerability in the Linux kernel for Ubuntu 17.04. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 17.04 for Ubuntu 16.04 LTS. A reference count bug was discovered in the Linux kernel ipx protocol stack. A local attacker could exploit this flaw to cause a denial of service or possibly other unspecified problems. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: linux-image-4.10.0-33-generic 4.10.0-33.37~16.04.1 linux-image-4.10.0-33-generic-lpae 4.10.0-33.37~16.04.1 linux-image-4.10.0-33-lowlatency 4.10.0-33.37~16.04.1 linux-image-generic-hwe-16.04 4.10.0.33.35 linux-image-generic-lpae-hwe-16.04 4.10.0.33.35 linux-image-lowlatency-hwe-16.04 4.10.0.33.35 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.
