"The version of OpenSSL installed on the remote host is prior to 0.9.7c. It is, therefore, affected by multiple
vulnerabilities as referenced in the 0.9.7c advisory.

  - Double free vulnerability in OpenSSL 0.9.7 allows remote attackers to cause a denial of service (crash)
    and possibly execute arbitrary code via an SSL client certificate with a certain invalid ASN.1 encoding.
    (CVE-2003-0545)

  - OpenSSL 0.9.6 and 0.9.7 does not properly track the number of characters in certain ASN.1 inputs, which
    allows remote attackers to cause a denial of service (crash) via an SSL client certificate that causes
    OpenSSL to read past the end of a buffer when the long form is used. (CVE-2003-0544)

  - Integer overflow in OpenSSL 0.9.6 and 0.9.7 allows remote attackers to cause a denial of service (crash)
    via an SSL client certificate with certain ASN.1 tag values. (CVE-2003-0543)

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