The version of OpenSSL installed on the remote host is prior to 0.9.8y. It is, therefore, affected by multiple vulnerabilities as referenced in the 0.9.8y advisory.
OpenSSL before 0.9.8y, 1.0.0 before 1.0.0k, and 1.0.1 before 1.0.1d does not properly perform signature verification for OCSP responses, which allows remote OCSP servers to cause a denial of service (NULL pointer dereference and application crash) via an invalid key. (CVE-2013-0166)
The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and other products, do not properly consider timing side-channel attacks on a MAC check requirement during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, aka the Lucky Thirteen issue. (CVE-2013-0169)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
