Note that successful exploitation of the most serious issues can result in arbitrary code execution.

Versions of OpenSSL prior to 1.0.1s, or 1.0.2g are unpatched for the following vulnerabilities :

According to its banner, the remote host is running a version of OpenSSL 1.0.2 prior to 1.0.2g. It is, therefore, affected by the following vulnerabilities :

  - A key disclosure vulnerability exists due to improper handling of cache-bank conflicts on the Intel Sandy-bridge microarchitecture. An attacker can exploit this to gain access to RSA key information. (CVE-2016-0702)

  - A double-free error exists due to improper validation of user-supplied input when parsing malformed DSA private keys. A remote attacker can exploit this to corrupt memory, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-0705)

  - A NULL pointer dereference flaw exists in the BN_hex2bn() and BN_dec2bn() functions. A remote attacker can exploit this to trigger a heap corruption, resulting in the execution of arbitrary code. (CVE-2016-0797)

  - A denial of service vulnerability exists due to improper handling of invalid usernames. A remote attacker can exploit this, via a specially crafted username, to leak 300 bytes of memory per connection, exhausting available memory resources. (CVE-2016-0798)

  - Multiple memory corruption issues exist that allow a remote attacker to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-0799)

  - A flaw exists that allows a cross-protocol Bleichenbacher padding oracle attack known as DROWN (Decrypting RSA with Obsolete and Weakened eNcryption). This vulnerability exists due to a flaw in the Secure Sockets Layer Version 2 (SSLv2) implementation, and it allows captured TLS traffic to be decrypted. A man-in-the-middle attacker can exploit this to decrypt the TSL connection by utilizing previously captured traffic and weak cryptography along with a series of specially crafted connections to an SSLv2 server that uses the same private key. (CVE-2016-0800)
