Vulnerabilidad fácilmente explotable permite a atacantes poco privilegiados con acceso a la red a través de múltiples protocolos, comprometer MySQL Server. Ataques exitosos de esta vulnerabilidad pueden resultar en capacidad no autorizada para provocar un cuelgue o bloqueo frecuentemente repetible (DOS completo) de MySQL Server. CVSS v3.0 Base Score 6.5 (Impacto de disponibilidad).

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.
