Detailed Description According to its banner, the remote web server uses a version of OpenSSL which is 1.0.1 prior to 1.0.1q. Such versions may be affected by the following vulnerabilities :

- A NULL pointer dereference flaw exists in file rsa_ameth.c when handling ASN.1 signatures that use the RSA PSS algorithm but are missing a mask generation function parameter. A remote attacker can exploit this to cause the signature verification routine to crash, leading to a denial of service. (CVE-2015-3194)

- A flaw exists in the ASN1_TFLG_COMBINE implementation in file tasn_dec.c related to handling malformed X509_ATTRIBUTE structures. A remote attacker can exploit this to cause a memory leak by triggering a decoding failure in a PKCS#7 or CMS application, resulting in a denial of service. (CVE-2015-3195)
