Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Security: Encryption). Supported versions that are affected are 5.7.16 and earlier. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of MySQL Server accessible data. CVSS v3.0 Base Score 2.4 (Confidentiality impacts).

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2886 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-mysql57-mysql (5.7.19).

    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)

    * 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)

    * 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)

    * 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.

    Bug Fix(es):

    * Prior to this update, the scl macros were not set for the rh-mysql57-mysqld@.service file, which     consequently made the service file unusable. This bug has been fixed, and rh-mysql57-mysqld@.service now     works as expected. (BZ#1452511)

    * 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#1452514)

The remote host is affected by the vulnerability described in GLSA-201702-17 (MySQL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in MySQL. Please review       the CVE identifiers referenced below for details.
  Impact :

    An attacker could possibly escalate privileges, gain access to critical       data or complete access to all MySQL server accessible data, or cause a       Denial of Service condition via unspecified vectors.
  Workaround :

    There is no known workaround at this time.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3174-1 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 5.5.54 in Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Ubuntu 16.04 LTS and Ubuntu     16.10 have been updated to MySQL 5.7.17.

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

  - An unspecified flaw exists in the DDL subcomponent that     allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2017-3273)

  - Multiple unspecified flaws exist in the Packaging     subcomponent that allow a local attacker to gain     elevated privileges. (CVE-2017-3291, CVE-2017-3312)

  - An unspecified flaw exists in the MyISAM subcomponent     that allows a local attacker to disclose sensitive     information. (CVE-2017-3313)

  - An unspecified flaw exists in the Logging subcomponent     that allows a local attacker to cause a denial of     service condition. (CVE-2017-3317)

  - An unspecified flaw exists in the Error Handling     subcomponent that allows a local attacker to disclose     sensitive information. (CVE-2017-3318)

  - An unspecified flaw exists in the X Plugin subcomponent     that allows an authenticated, remote attacker to     disclose sensitive information. (CVE-2017-3319)

  - An unspecified flaw exists in the Security: Encryption     subcomponent that allows an authenticated, remote     attacker to disclose sensitive information.
    (CVE-2017-3320)

  - A local privilege escalation vulnerability exists in the     mysqld_safe component due to unsafe use of the 'rm' and     'chown' commands. A local attacker can exploit this to     gain elevated privileges.

  - An unspecified flaw exists in the mysqld_safe component     that allows an authenticated, remote attacker to have an     unspecified impact.

  - An overflow condition exists in the Optimizer component     due to improper validation of user-supplied input when     handling nested expressions. An authenticated, remote     attacker can exploit this to cause a stack-based buffer     overflow, resulting in a denial of service condition.

  - An unspecified flaw exists when handling a CREATE TABLE     query with a DATA DIRECTORY clause. An authenticated,     remote attacker can exploit this to gain elevated     privileges.
