| Detailed Description |
The version of MySQL running on the remote host is 5.7.x prior to 5.7.12. It is, therefore, affected by multiple vulnerabilities :
- A cipher algorithm downgrade vulnerability exists in the bundled version of OpenSSL due to a flaw that is triggered when handling cipher negotiation. A remote attacker can exploit this to negotiate SSLv2 ciphers and complete SSLv2 handshakes even if all SSLv2 ciphers have been disabled on the server. Note that this vulnerability only exists if the SSL_OP_NO_SSLv2 option has not been disabled. (CVE-2015-3197)
- An unspecified flaw exists in the Pluggable Authentication subcomponent that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2016-0639)
- An unspecified flaw exists in the Federated subcomponent that allows an authenticated, remote attacker to impact integrity and availability. (CVE-2016-0642)
- An unspecified flaw exists in the DML subcomponent that allows an authenticated, remote attacker to disclose sensitive information. (CVE-2016-0643)
- An unspecified flaw exists in the FTS subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-0647)
- An unspecified flaw exists in the PS subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-0647)
- An unspecified flaw exists in the InnoDB subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-0655)
- An unspecified flaw exists in the JSON subcomponent that allows an authenticated, remote attacker to disclose sensitive information. (CVE-2016-0657)
- An unspecified flaw exists in the Optimizer subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-0659)
- An unspecified flaw exists in the Partition subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-0662)
- An unspecified flaw exists in the Security: Privileges subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-0666)
- An unspecified flaw exists in the Locking subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-0667)
- A key disclosure vulnerability exists in the bundled version of OpenSSL 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 in the bundled version of OpenSSL 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 bundled version of OpenSSL 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 in the bundled version of OpenSSL 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)
* Note: This check solely relied on the banner of the remote MySQL server to assess this vulnerability, so this might be a false positive.
