high Nessus Plugin ID 152078

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-2718 advisory.

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. For Debian 9 stretch, these problems have been fixed in version 3.20210608.2~deb9u2.
Please note that one of the processors is not receiving this update and so the users of 0x906ea processors that don't have Intel Wireless on-board can use the package from the buster-security, instead. We recommend that you upgrade your intel-microcode packages. For the detailed security status of intel- microcode please refer to its security tracker page at: https://security-tracker.debian.org/tracker/intel- microcode Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

Solution

Upgrade the intel-microcode packages.

For Debian 9 stretch, these problems have been fixed in version 3.20210608.2~deb9u2.
