medium Nessus Plugin ID 181433


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


The remote AlmaLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2023:5080 advisory.

- A flaw was found in Keylime. Due to their blocking nature, the Keylime registrar is subject to a remote denial of service against its SSL connections. This flaw allows an attacker to exhaust all available connections. (CVE-2023-38200)

- A flaw was found in the Keylime registrar that could allow a bypass of the challenge-response protocol during agent registration. This issue may allow an attacker to impersonate an agent and hide the true status of a monitored machine if the fake agent is added to the verifier list by a legitimate user, resulting in a breach of the integrity of the registrar database. (CVE-2023-38201)

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