The remote host is missing an update for the 'dovecot' package(s) announced via the FEDORA-2024-ba5bb9f63a advisory. A large number of address headers in email resulted in excessive CPU usage. Abnormally large email headers are now truncated or discarded, with a limit of 10MB on a single header and 50MB for all the headers of all the parts of an email
