"The remote MiracleLinux 3 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2009-72:01 advisory.

    The cyrus-imapd package contains the core of the Cyrus IMAP server. It is a scaleable enterprise mail
    system designed for use from small to large enterprise environments using standards-based internet mail
    technologies.
    A full Cyrus IMAP implementation allows a seamless mail and bulletin board environment to be set up across
    multiple servers. It differs from other IMAP server implementations in that it is run on sealed servers,
    where users are not normally permitted to log in and have no system account on the server. The mailbox
    database is stored in parts of the filesystem that are private to the Cyrus IMAP server. All user access
    to mail is through software using the IMAP, POP3 or KPOP protocols. It also includes support for virtual
    domains, NNTP, mailbox annotations, and much more. The private mailbox database design gives the server
    large advantages in efficiency, scalability and administratability. Multiple concurrent read/write
    connections to the same mailbox are permitted. The server supports access control lists on mailboxes and
    storage quotas on mailbox hierarchies.
    The Cyrus IMAP server supports the IMAP4rev1 protocol described in RFC 3501. IMAP4rev1 has been approved
    as a proposed standard. It supports any authentication mechanism available from the SASL library,
    imaps/pop3s/nntps (IMAP/POP3/NNTP encrypted using SSL and TLSv1) can be used for security. The server
    supports single instance store where possible when an email message is addressed to multiple recipients,
    SIEVE provides server side email filtering.
    Fixed bugs:
    CVE-2009-0688
    Multiple buffer overflows in the CMU Cyrus SASL library before 2.1.23 might allow remote attackers to
    execute arbitrary code or cause a denial of service (application crash) via strings that are used as input
    to the sasl_encode64 function in lib/saslutil.c.

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

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