Descriptions

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Pluggable Auth). 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). NOTE: the previous information is from the April 2017 CPU. Oracle has not commented on third-party claims that this issue is an integer overflow in sql/auth/sql_authentication.cc which allows remote attackers to cause a denial of service via a crafted authentication packet.

Se ha encontrado una vulnerabilidad en el componente MySQL Server de Oracle MySQL (subcomponente: Server: Pluggable Auth). Las versiones compatibles que se ven afectadas son versión 5.6.35 y anteriores y versión 5.7.17 y anteriores. La vulnerabilidad fácilmente "explotable" permite que un atacante no autenticado con acceso a la red por medio de múltiples protocolos ponga en peligro el servidor MySQL. Los ataques con éxito de esta vulnerabilidad pueden resultar en una capacidad no autorizada para generar una suspensión o un bloqueo repetible con frecuencia (DoS completo) de 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). NOTE: the previous information is from the April 2017 CPU. NOTA: la información anterior es de la CPU de abril de 2017. Oracle no ha comentado sobre las afirmaciones de terceros de que este problema es un desbordamiento de enteros en sql/auth/sql_authentication.cc que permite a los atacantes remotos generar una Denegación de Servicio (DoS) por medio de un paquete de autenticación creado.

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.

MySQL versions 5.6.35 and below and 5.7.17 and below suffer from an integer overflow vulnerability.
