Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: DDL). Supported versions that are affected are 5.6.34 and earlier and 5.7.16 and earlier. Easily exploitable vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS v3.0 Base Score 6.5 (Availability impacts).

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.

Oracle reports :

No further details have been provided in the Critical Patch Update

The version of MySQL installed on the remote host is version 5.6.x prior to 5.6.35 and is affected by multiple issues :

 - A flaw exists in 'mysqld_safe' that is due to the unsafe use of 'rm' and 'chown'. This may allow an authenticated local attacker to gain elevated privileges.
 - An unspecified flaw exists in 'mysqld_safe' that is due to the program ignoring the current working directory. This may allow an authenticated attacker to have an unspecified impact. No further details have been provided.
 - An overflow condition exists in the Optimizer. The issue is triggered as certain input is not properly validated when handling nested expressions. This may allow an authenticated attacker to cause a stack-based buffer overflow, resulting in a denial of service.
 - A flaw exists that is triggered during the handling of a 'CREATE TABLE' query with a 'DATA DIRECTORY' clause. This may allow an authenticated attacker to gain elevated privileges.
 - An unspecified flaw exists related to the Security:Encryption subcomponent. This may allow a context-dependent attacker to cause a denial of service. No further details have been provided by the vendor.
 - An unspecified flaw exists related to the DDL subcomponent. This may allow an authenticated attacker to cause a denial of service. No further details have been provided by the vendor.
 - An unspecified flaw exists related to the MyISAM subcomponent. This may allow a local attacker to gain access to sensitive information. No further details have been provided by the vendor.
 - An unspecified flaw exists related to the Replication subcomponent. This may allow an authenticated attacker to cause a denial of service. No further details have been provided by the vendor.
