Title:	Ubuntu: Security Advisory (USN-4628-2)
Summary:	The remote host is missing an update for the 'intel-microcode' package(s) announced via the USN-4628-2 advisory.
Description:	Summary: The remote host is missing an update for the 'intel-microcode' package(s) announced via the USN-4628-2 advisory. Vulnerability Insight: USN-4628-1 provided updated Intel Processor Microcode. Unfortunately, that update prevented certain processors in the Intel Tiger Lake family from booting successfully. This update reverts the microcode update for the Tiger Lake processor family. Please note that the 'dis_ucode_ldr' kernel command line option can be added in the boot menu to disable microcode loading for system recovery. We apologize for the inconvenience. Original advisory details: Moritz Lipp, Michael Schwarz, Andreas Kogler, David Oswald, Catherine Easdon, Claudio Canella, and Daniel Gruss discovered that the Intel Running Average Power Limit (RAPL) feature of some Intel processors allowed a side- channel attack based on power consumption measurements. A local attacker could possibly use this to expose sensitive information. (CVE-2020-8695) Ezra Caltum, Joseph Nuzman, Nir Shildan and Ofir Joseff discovered that some Intel(R) Processors did not properly remove sensitive information before storage or transfer in some situations. A local attacker could possibly use this to expose sensitive information. (CVE-2020-8696) Ezra Caltum, Joseph Nuzman, Nir Shildan and Ofir Joseff discovered that some Intel(R) Processors did not properly isolate shared resources in some situations. A local attacker could possibly use this to expose sensitive information. (CVE-2020-8698) Affected Software/OS: 'intel-microcode' package(s) on Ubuntu 14.04, Ubuntu 16.04, Ubuntu 18.04, Ubuntu 20.04, Ubuntu 20.10. Solution: Please install the updated package(s).
