Protocol TCP

Detailed Description According to its banner, the remote web server uses a version of OpenSSL which is 1.0.0 prior to 1.0.0t. Such versions may be affected by the following vulnerabilities :

- 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)

- A race condition exists in s3_clnt.c that is triggered when PSK identity hints are incorrectly updated in the parent SSL_CTX structure when they are received by a multi-threaded client. A remote attacker can exploit this, via a crafted ServerKeyExchange message, to cause a double-free memory error, resulting in a denial of service. (CVE-2015-3196)
