Heap-based buffer overflow in Oracle MySQL 5.5.19 and other versions through 5.5.28, and MariaDB 5.5.28a and possibly other versions, allows remote authenticated users to cause a denial of service (memory corruption and crash) and possibly execute arbitrary code, as demonstrated using certain variations of the (1) USE, (2) SHOW TABLES, (3) DESCRIBE, (4) SHOW FIELDS FROM, (5) SHOW COLUMNS FROM, (6) SHOW INDEX FROM, (7) CREATE TABLE, (8) DROP TABLE, (9) ALTER TABLE, (10) DELETE FROM, (11) UPDATE, and (12) SET PASSWORD commands.

Stack-based buffer overflow in the acl_get function in Oracle MySQL 5.5.19 and other versions through 5.5.28, and 5.1.53 and other versions through 5.1.66, and MariaDB 5.5.2.x before 5.5.28a, 5.3.x before 5.3.11, 5.2.x before 5.2.13 and 5.1.x before 5.1.66, allows remote authenticated users to execute arbitrary code via a long argument to the GRANT FILE command.

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: InnoDB). Supported versions that are affected are 5.7.19 and earlier. Easily exploitable vulnerability allows high 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 3.0 Base Score 4.9 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H).

Unspecified vulnerability in Oracle MySQL Server 5.6.25 and earlier allows remote authenticated users to affect availability via unknown vectors related to Server : InnoDB.

Unspecified vulnerability in Oracle MySQL 5.5.51 and earlier allows remote authenticated users to affect availability via vectors related to DML.

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Charsets). Supported versions that are affected are 5.5.53 and earlier. Difficult to exploit vulnerability allows high 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 4.4 (Availability impacts).

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: InnoDB). Supported versions that are affected are 5.6.37 and earlier and 5.7.19 and earlier. Difficult to exploit vulnerability allows high 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 3.0 Base Score 4.4 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H).

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: DDL). Supported versions that are affected are 5.5.57 and earlier 5.6.37 and earlier 5.7.19 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 3.0 Base Score 6.5 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Client programs). Supported versions that are affected are 5.5.57 and earlier, 5.6.37 and earlier and 5.7.19 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 access to critical data or complete access to all MySQL Server accessible data. CVSS 3.0 Base Score 6.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).

The do_ssl3_write function in s3_pkt.c in OpenSSL 1.x through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, does not properly manage a buffer pointer during certain recursive calls, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via vectors that trigger an alert condition.
