SUSE SLED12 / SLES12 Security Update : ucode-intel (SUSE-SU-2018:0006-1) (Spectre)

Medium Nessus Plugin ID 105539

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for ucode-intel fixes the following issues: The CPU microcode for Haswell-X, Skylake-X and Broadwell-X chipsets was updated to report both branch prediction control via CPUID flag and ability to control branch prediction via an MSR register. This update is part of a mitigation for a branch predictor based information disclosure attack, and needs additional code in the Linux Kernel to be active (bsc#1068032 CVE-2017-5715)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
