An update that fixes one vulnerability is now available.
Description:
This update for microcode_ctl fixes the following issues:
Added microcode_amd_fam17h.bin (bsc#1068032 CVE-2017-5715)
This new firmware disables branch prediction on AMD family 17h processor.
Also the CPU microcode for Intel 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.
