NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-keylime package and not the python3-keylime package as distributed by Oracle. See How to fix? for Oracle:10 relevant fixed versions and status.

A flaw was found in Keylime. An attacker with root access on an enrolled monitored machine, where the Keylime agent runs, can exploit a vulnerability in the Keylime verifier. The verifier uses a hardcoded challenge nonce for Trusted Platform Module (TPM) quote attestation instead of a cryptographically random value. This allows the attacker to stockpile valid TPM quotes and replay them to evade detection after compromising the system. This issue affects only the push model deployment.
