medium Nessus Plugin ID 207723

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7033-1 advisory.

 It was discovered that some Intel(R) Processors did not properly restrict access to the Running Average Power Limit (RAPL) interface. This may allow a local privileged attacker to obtain sensitive information.
 (CVE-2024-23984)

 It was discovered that some Intel(R) Processors did not properly implement finite state machines (FSMs) in hardware logic. This may allow a local privileged attacker to cause a denial of service (system crash).
 (CVE-2024-24968)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected intel-microcode package.
