Ubuntu 20.04 LTS / 22.04 LTS / 23.10 / 24.04 LTS : TPM2 Software Stack vulnerabilities (USN-6796-1)

medium Nessus Plugin ID 198063

Language:

Synopsis

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

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6796-1 advisory.

 Fergus Dall discovered that TPM2 Software Stack did not properly handle layer arrays. An attacker could possibly use this issue to cause

 TPM2 Software Stack to crash, resulting in a denial of service, or

 possibly execute arbitrary code. (CVE-2023-22745)

 Jurgen Repp and Andreas Fuchs discovered that TPM2 Software Stack did not

 validate the quote data after deserialization. An attacker could generate an arbitrary quote and cause TPM2 Software Stack to have unknown behavior.

 (CVE-2024-29040)

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 packages.
