| Description: | Summary:
The remote host is missing an update for the 'intel-microcode' package(s) announced via the USN-4182-3 advisory.
Vulnerability Insight:
USN-4182-1 provided updated Intel Processor Microcode. A regression
was discovered that caused some Skylake processors to hang after
a warm reboot. This update reverts the microcode for that specific
processor family.
We apologize for the inconvenience.
Original advisory details:
Stephan van Schaik, Alyssa Milburn, Sebastian Osterlund, Pietro Frigo,
Kaveh Razavi, Herbert Bos, Cristiano Giuffrida, Giorgi Maisuradze, Moritz
Lipp, Michael Schwarz, Daniel Gruss, and Jo Van Bulck discovered that Intel
processors using Transactional Synchronization Extensions (TSX) could
expose memory contents previously stored in microarchitectural buffers to a
malicious process that is executing on the same CPU core. A local attacker
could use this to expose sensitive information. (CVE-2019-11135)
It was discovered that certain Intel Xeon processors did not properly
restrict access to a voltage modulation interface. A local privileged
attacker could use this to cause a denial of service (system crash).
