The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2023:7836 advisory.

  - A flaw was found in avahi in versions 0.6 up to 0.8. The event used to signal the termination of the     client connection on the avahi Unix socket is not correctly handled in the client_work function, allowing     a local attacker to trigger an infinite loop. The highest threat from this vulnerability is to the     availability of the avahi service, which becomes unresponsive after this flaw is triggered.
