Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: C API). Supported versions that are affected are 5.5.55 and earlier and 5.6.35 and earlier. Difficult to exploit vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all MySQL Server accessible data. CVSS 3.0 Base Score 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N). NOTE: the previous information is from the April 2017 CPU. Oracle has not commented on third-party claims that this issue allows man-in-the-middle attackers to hijack the authentication of users by leveraging incorrect ordering of security parameter verification in a client, aka, "The Riddle".

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2787 advisory.

    MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon, mysqld,     and many client programs.

    The following packages have been upgraded to a later upstream version: rh-mysql56-mysql (5.6.37).

    Security Fix(es):

    * An integer overflow flaw leading to a buffer overflow was found in the way MySQL parsed connection     handshake packets. An unauthenticated remote attacker with access to the MySQL port could use this flaw to     crash the mysqld daemon. (CVE-2017-3599)

    * It was discovered that the mysql and mysqldump tools did not correctly handle database and table names     containing newline characters. A database user with privileges to create databases or tables could cause     the mysql command to execute arbitrary shell or SQL commands while restoring database backup created using     the mysqldump tool. (CVE-2016-5483, CVE-2017-3600)

    * Multiple flaws were found in the way the MySQL init script handled initialization of the database data     directory and permission setting on the error log file. The mysql operating system user could use these     flaws to escalate their privileges to root. (CVE-2017-3265)

    * It was discovered that the mysqld_safe script honored the ledir option value set in a MySQL     configuration file. A user able to modify one of the MySQL configuration files could use this flaw to     escalate their privileges to root. (CVE-2017-3291)

    * It was discovered that the MySQL client command line tools only checked after authentication whether     server supported SSL. A man-in-the-middle attacker could use this flaw to hijack client's authentication     to the server even if the client was configured to require SSL connection. (CVE-2017-3305)

    * Multiple flaws were found in the way the mysqld_safe script handled creation of error log file. The     mysql operating system user could use these flaws to escalate their privileges to root. (CVE-2017-3312)

    * A flaw was found in the way MySQL client library (libmysqlclient) handled prepared statements when     server connection was lost. A malicious server or a man-in-the-middle attacker could possibly use this     flaw to crash an application using libmysqlclient. (CVE-2017-3302)

    * This update fixes several vulnerabilities in the MySQL database server. Information about these flaws     can be found on the Oracle Critical Patch Update Advisory pages listed in the References section.

    Red Hat would like to thank Pali Rohr for reporting CVE-2017-3305.

    Bug Fix(es):

    * Previously, the md5() function was blocked by MySQL in FIPS mode because the MD5 hash algorithm is     considered insecure. Consequently, the mysqld daemon failed with error messages when FIPS mode was     enabled. With this update, md5() is allowed in FIPS mode for non-security operations. Note that users are     able to use md5() for security purposes but such usage is not supported by Red Hat. (BZ#1452469)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

This update for mysql-community-server to version 5.6.36 fixes the following issues :

These security issues were fixed :

  - CVE-2016-5483: Mysqldump failed to properly quote     certain identifiers in SQL statements written to the     dump output, allowing for execution of arbitrary     commands (bsc#1029014)

  - CVE-2017-3305: MySQL client sent authentication request     unencrypted even if SSL was required (aka Ridddle)     (bsc#1029396).

  - Change permissions of the configuration dir/files to     755/644. Please note that storing the password in the     /etc/my.cnf file is not safe. Use for example an option     file that is accessible only by yourself (boo#889126)

The version of MySQL running on the remote host is 5.6.x prior to 5.6.36. It is, therefore, affected by multiple vulnerabilities :

  - A use-after-free error exists in the     mysql_prune_stmt_list() function in client.c that allows     an authenticated, remote attacker to cause a denial of     service condition. (CVE-2017-3302)

  - 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)

  - An authentication information disclosure vulnerability,     known as Riddle, exists due to authentication being     performed prior to security parameter verification. A     man-in-the-middle (MitM) attacker can exploit this     vulnerability to disclose sensitive authentication     information, which the attacker can later use for     authenticating to the server. (CVE-2017-3305)

  - 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-2017-3456)

  - 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-2017-3452, CVE-2017-3453)

  - 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)

  - 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 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.
