According to its banner, the remote web server is running a version of OpenSSL prior to 0.9.8y. The OpenSSL library is, therefore, reportedly affected by the following vulnerabilities :
An error exists related to the handling of OCSP response verification that could allow denial of service attacks.
(CVE-2013-0166)
An error exists related to the SSL/TLS/DTLS protocols, CBC mode encryption and response time. An attacker could obtain plaintext contents of encrypted traffic via timing attacks. (CVE-2013-0169)
