Test ID:1.3.6.1.4.1.25623.1.0.704934
Category:Debian Local Security Checks
Title:Debian: Security Advisory for intel-microcode (DSA-4934-1)
Summary:The remote host is missing an update for the 'intel-microcode'; package(s) announced via the DSA-4934-1 advisory.
Description:Summary:
The remote host is missing an update for the 'intel-microcode'
package(s) announced via the DSA-4934-1 advisory.

Vulnerability Insight:
This update ships updated CPU microcode for some types of Intel CPUs and
provides mitigations for security vulnerabilities which could result in
privilege escalation in combination with VT-d and various side channel
attacks.

Affected Software/OS:
'intel-microcode' package(s) on Debian Linux.

Solution:
For the stable distribution (buster), these problems have been fixed in
version 3.20210608.2~
deb10u1.

Note that there are two reported regressions, for some CoffeeLake CPUs
this update may break iwlwifi
([link moved to references])
and some for Skylake R0/D0 CPUs on systems using a very outdated firmware/BIOS,
the system may hang on boot:

If you are affected by those issues, you can recover by disabling microcode
loading on boot (as documented in README.Debian, also available online at
[link moved to references])
We recommend that you upgrade your intel-microcode packages.
