========================================================================== Ubuntu Security Notice USN-3548-1 January 26, 2018
linux vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.10
Summary:
The system could be made to crash or run programs as an administrator.
Software Description: - linux: Linux kernel
Details:
Jay Vosburgh discovered a logic error in the x86-64 syscall entry implementation in the Linux kernel, introduced as part of the mitigations for the Spectre vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 17.10: linux-image-4.13.0-32-generic 4.13.0-32.35 linux-image-4.13.0-32-lowlatency 4.13.0-32.35 linux-image-generic 4.13.0.32.34 linux-image-lowlatency 4.13.0.32.34
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.
