A flaw was found in Keylime, a remote attestation solution, where strict type checking introduced in version 7.12.0 prevents the registrar from reading database entries created by previous versions, for example, 7.11.0. Specifically, older versions store agent registration data as bytes, whereas the updated registrar expects str. This issue leads to an exception when processing agent registration requests, causing the agent to fail.

The remote SUSE Linux SLES16 / SLES_SAP16 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:21194-1 advisory.

    Update to version 7.13.0+40.

    Security issues fixed:

    - CVE-2025-13609: possible agent identity takeover due to registrar allowing the registration of agents     with duplicate       UUIDs (bsc#1254199).
    - CVE-2025-1057: registrar denial-of-service due to backward incompatibility in database type handling     (bsc#1237153).

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

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