The version of OpenSSL installed on the remote host is prior to 0.9.6k. It is, therefore, affected by multiple vulnerabilities as referenced in the 0.9.6k advisory.
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.
