Descriptions

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Memcached). Supported versions that are affected are 5.6.35 and earlier and 5.7.17 and earlier. Easily "exploitable" vulnerability allows unauthenticated 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 7.5 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

Vulnerabilidad en el componente MySQL Server de Oracle MySQL (subcomponente: Server: Memcached). Las versiones compatibles que son afectadas son 5.6.35 y versiones anteriores, 5.7.17 y veriones anteriores. La vulnerabilidad fácilmente "explotable" permite a un atacante no autenticado con acceso a la red comprometer MySQL Server a través de múltiples protocolos. Los ataques exitosos de esta vulnerabilidad pueden resultar en capacidad no autorizada para provocar un cuelgue o un bloqueo frecuentemente repetible (DOS completo) de MySQL Server. CVSS 3.0 Base Score 7.5 (Impactos de disponibilidad). Vector CVSS: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

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. Security Fix: 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.
