Oracle reports :

This Critical Patch Update contains 39 new security fixes for Oracle MySQL. 11 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials.

The version of MySQL running on the remote host is 5.7.x prior to 5.7.18. It is, therefore, affected by multiple vulnerabilities :

  - A carry propagation error exists in the OpenSSL     component in the Broadwell-specific Montgomery     multiplication procedure when handling input lengths     divisible by but longer than 256 bits. This can result     in transient authentication and key negotiation failures     or reproducible erroneous outcomes of public-key     operations with specially crafted input. A     man-in-the-middle attacker can possibly exploit this     issue to compromise ECDH key negotiations that utilize     Brainpool P-512 curves. (CVE-2016-7055)

  - Multiple unspecified flaws exist in the DML subcomponent     that allow an authenticated, remote attacker to cause a     denial of service condition. (CVE-2017-3308,     CVE-2017-3331, CVE-2017-3456, CVE-2017-3457,     CVE-2017-3458)

  - Multiple unspecified flaws exist in the Optimizer     subcomponent that allow an authenticated, remote     attacker to cause a denial of service condition.
    (CVE-2017-3309, CVE-2017-3453, CVE-2017-3459)

  - An unspecified flaw exists in the Thread Pooling     subcomponent that allows an unauthenticated, remote     attacker to cause a denial of service condition.
    (CVE-2017-3329)

  - An unspecified flaw exists in the Memcached subcomponent     that allows an unauthenticated, remote attacker to cause     a denial of service condition. (CVE-2017-3450)

  - An unspecified flaw exists in the InnoDB subcomponent     that allows an authenticated, remote attacker to insert     and delete data contained in the database or cause a     denial of service condition. (CVE-2017-3454)

  - An unspecified flaw exists in the 'Security: Privileges'     subcomponent that allows an authenticated, remote     attacker to insert or delete data contained in the     database or disclose sensitive information.
    (CVE-2017-3455)

  - An unspecified flaw exists in the Audit Plug-in     subcomponent that allows an authenticated, remote     attacker to cause a denial of service condition.
    (CVE-2017-3460)

  - Multiple unspecified flaws exist in the     'Security: Privileges' subcomponent that allow an     authenticated, remote attacker to cause a denial of     service condition. (CVE-2017-3461, CVE-2017-3462,     CVE-2017-3463)

  - An unspecified flaw exists in the DDL subcomponent that     allows an authenticated, remote attacker to update,     insert, or delete data contained in the database.
    (CVE-2017-3464)

  - An unspecified flaw exists in the 'Security: Privileges'     subcomponent that allows an authenticated, remote     attacker to update, insert, or delete data contained in     the database. (CVE-2017-3465)

  - An unspecified flaw exists in the C API subcomponent     that allows an unauthenticated, remote attacker to     disclose sensitive information. (CVE-2017-3467)

  - An unspecified flaw exists in the 'Security: Encryption'     subcomponent that allows an authenticated, remote     attacker to update, insert, or delete data contained in     the database. (CVE-2017-3468)

  - An unspecified flaw exists in the Pluggable Auth     subcomponent that allows an unauthenticated, remote     attacker to cause a denial of service condition.
    (CVE-2017-3599)

  - An unspecified flaw exists in the 'Client mysqldump'     subcomponent that allows an authenticated, remote     attacker to execute arbitrary code. (CVE-2017-3600)

  - An out-of-bounds read error exists in the OpenSSL     component when handling packets using the     CHACHA20/POLY1305 or RC4-MD5 ciphers. An     unauthenticated, remote attacker can exploit this, via     specially crafted truncated packets, to cause a denial     of service condition. (CVE-2017-3731)

  - A carry propagating error exists in the OpenSSL     component in the x86_64 Montgomery squaring     implementation that may cause the BN_mod_exp() function     to produce incorrect results. An unauthenticated, remote     attacker with sufficient resources can exploit this to     obtain sensitive information regarding private keys.
    (CVE-2017-3732)

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

Several issues have been discovered in the MySQL database server. The vulnerabilities are addressed by upgrading MySQL to the new upstream version 5.5.55, which includes additional changes, such as performance improvements, bug fixes, new features, and possibly incompatible changes. Please see the MySQL 5.5 Release Notes and Oracle's Critical Patch Update advisory for further details :

https://dev.mysql.com/doc/relnotes/mysql/5.5/en/news-5-5-55.html http://www.oracle.com/technetwork/security-advisory/cpuapr2017-3236618 .html

For Debian 7 'Wheezy', these problems have been fixed in version 5.5.55-0+deb7u1.

We recommend that you upgrade your mysql-5.5 packages.
