"The version of OpenSSL installed on the remote host is prior to 0.9.8n. It is, therefore, affected by multiple
vulnerabilities as referenced in the 0.9.8n advisory.

  - The ssl3_get_record function in ssl/s3_pkt.c in OpenSSL 0.9.8f through 0.9.8m allows remote attackers to
    cause a denial of service (crash) via a malformed record in a TLS connection that triggers a NULL pointer
    dereference, related to the minor version number. NOTE: some of these details are obtained from third
    party information. (CVE-2010-0740)

  - The kssl_keytab_is_available function in ssl/kssl.c in OpenSSL before 0.9.8n, when Kerberos is enabled but
    Kerberos configuration files cannot be opened, does not check a certain return value, which allows remote
    attackers to cause a denial of service (NULL pointer dereference and daemon crash) via SSL cipher
    negotiation, as demonstrated by a chroot installation of Dovecot or stunnel without Kerberos configuration
    files inside the chroot. (CVE-2010-0433)

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