The version of OpenSSL installed on the remote host is prior to 1.0.1c. It is, therefore, affected by a vulnerability as referenced in the 1.0.1c advisory.

  • Integer underflow in OpenSSL before 0.9.8x, 1.0.0 before 1.0.0j, and 1.0.1 before 1.0.1c, when TLS 1.1, TLS 1.2, or DTLS is used with CBC encryption, allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via a crafted TLS packet that is not properly handled during a certain explicit IV calculation. (CVE-2012-2333)

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