I'm running DELL OptiPlex 7040 (Ubuntu 18.04.2) and recently a 0.1.14.0 bios update arrived. It's description is:
This stable release fixes the following issues: • Firmware updates to address security advisory INTEL-SA-00185 (CVE-2018-12188 CVE-2018-12190 CVE-2018-12191 CVE-2018-12192 CVE-2018-12199 CVE-2018-12198 CVE-2018-12200 CVE-2018-12187 CVE-2018-12196 CVE-2018-12185).
Luckily rebooting loads system without problems. There were no issues with previous updates. If anyone has any insights, thanks in advance!
