"The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a
vulnerability as referenced in the 14908bda-232b-11ef-b621-00155d645102 advisory.

    Cyrus IMAP 3.8.3 Release Notes states:
    Fixed CVE-2024-34055: Cyrus-IMAP through 3.8.2 and 3.10.0-beta2 allow authenticated attackers to cause
    unbounded memory allocation by sending many LITERALs in a single command.
    The IMAP protocol allows for command arguments to be LITERALs of negotiated length, and for these the
    server allocates memory to receive the content before instructing the client to proceed. The allocated
    memory is released when the whole command has been received and processed.
    The IMAP protocol has a number commands that specify an unlimited number of arguments, for example SEARCH.
    Each of these arguments can be a LITERAL, for which memory will be allocated and not released until the
    entire command has been received and processed. This can run a server out of memory, with varying
    consequences depending on the server's OOM policy.

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

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
