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

  - Multiple integer signedness errors in crypto/buffer/buffer.c in OpenSSL 0.9.8v allow remote attackers to
    conduct buffer overflow attacks, and cause a denial of service (memory corruption) or possibly have
    unspecified other impact, via crafted DER data, as demonstrated by an X.509 certificate or an RSA public
    key. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-2110. (CVE-2012-2131)

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