Oracle reports reports :

Critical Patch Update contains 31 new security fixes for Oracle MySQL 5.5.48, 5.6.29, 5.7.11 and earlier

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)

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

  - A flaw exists in the bundled version of OpenSSL 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 TLS 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)

  - A man-in-the-middle spoofing vulnerability exists due to     the server hostname not being verified to match a domain     name in the Subject's Common Name (CN) or SubjectAltName     field of the X.509 certificate. A man-in-the-middle     attacker can exploit this, by spoofing the TLS/SSL     server via a certificate that appears valid, to disclose     sensitive information or manipulate transmitted data.
    (CVE-2016-2047)

  - An unspecified flaw exists in the Optimizer subcomponent     that allow an authenticated, remote attacker to cause a     denial of service condition. (CVE-2017-10378)

  - A flaw exists related to certificate validation due to     the server hostname not being verified to match a domain     name in the X.509 certificate. A man-in-the-middle     attacker can exploit this, by spoofing the TLS/SSL     server via a certificate that appears valid, to disclose     sensitive information or manipulate data.

  - An integer overflow condition exists that is triggered     due to improper validation of user-supplied input when     processing client handshakes. An authenticated, remote     attacker can exploit this to cause the server to exit,     resulting in a denial of service condition.

  - An information disclosure vulnerability exists due to     overly verbose error messages returning part of the SQL     statement that produced them. An authenticated, remote     attacker can exploit this to disclose sensitive     information.

  - A flaw exists in InnoDB that is triggered during the     handling of an ALTER TABLE or ADD COLUMN operation on a     table with virtual columns. An authenticated, remote     attacker can exploit this to crash the server, resulting     in a denial of service condition.

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2954-1 advisory.

    Multiple security issues were discovered in MySQL and this update includes new upstream MySQL versions to     fix these issues.

    MySQL has been updated to 5.7.12 in Ubuntu 16.04 LTS.

    In addition to security fixes, the updated packages contain bug fixes, new features, and possibly     incompatible changes.

    Please see the following for more information:
    http://dev.mysql.com/doc/relnotes/mysql/5.7/en/news-5-7-12.html     http://www.oracle.com/technetwork/security-advisory/cpuapr2016v3-2985753.html

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
