Synopsis

The remote Debian host is missing a security update.

Description

DLA-1789-1 shipped updated CPU microcode for most types of Intel CPUs as mitigations for the MSBDS, MFBDS, MLPDS and MDSUM hardware vulnerabilities.

This update provides additional support for some Sandybridge server and Core-X CPUs which were not covered in the original May microcode release. For a list of specific CPU models now supported please refer to the entries listed under CPUID 206D6 and 206D7 at https://www.intel.com/content/dam/www/public/us/en/documents/corporate
-information/SA00233-microcode-update-guidance_05132019.pdf

For Debian 8 'Jessie', these problems have been fixed in version 3.20190618.1~deb8u1 of the intel-microcode package.

We recommend that you upgrade your intel-microcode packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected intel-microcode package.
