security advisorycriticalDoSUbuntu 16.10: USN-3251-1 Critical: Kernel DoS And Privilege Escalation
The system could be made to crash or run programs as an administrator.. =========================================================================Ubuntu Security Notice USN-3251-1 March 29, 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: It was discovered that the xfrm framework for transforming packets in the Linux kernel did not properly validate data received from user space. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code with administrative privileges. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.10: linux-image-4.8.0-1032-raspi2 4.8.0-1032.35 linux-image-4.8.0-45-generic 4.8.0-45.48 linux-image-4.8.0-45-generic-lpae 4.8.0-45.48 linux-image-4.8.0-45-lowlatency 4.8.0-45.48 linux-image-4.8.0-45-powerpc-e500mc 4.8.0-45.48 linux-image-4.8.0-45-powerpc-smp 4.8.0-45.48 linux-image-generic 4.8.0.45.57 linux-image-generic-lpae 4.8.0.45.57 linux-image-lowlatency 4.8.0.45.57 linux-image-powerpc-e500mc 4.8.0.45.57 linux-image-powerpc-smp 4.8.0.45.57 linux-image-raspi2 4.8.0.1032.36 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 automaticallyperform this as well.

The system could be made to run programs as an administrator.. =========================================================================Ubuntu Security Notice USN-2601-1 May 05, 2015 linux vulnerability ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 15.04 Summary: The system could be made to run programs as an administrator. Software Description: - linux: Linux kernel Details: A race condition between chown() and execve() was discovered in the Linux kernel. A local attacker could exploit this race by using chown on a setuid-user-binary to gain administrative privileges.

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.
