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

  - OpenSSL before 0.9.7, 0.9.7 before 0.9.7k, and 0.9.8 before 0.9.8c, when using an RSA key with exponent 3,
    removes PKCS-1 padding before generating a hash, which allows remote attackers to forge a PKCS #1 v1.5
    signature that is signed by that RSA key and prevents OpenSSL from correctly verifying X.509 and other
    certificates that use PKCS #1. (CVE-2006-4339)

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