Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: UDF). Supported versions that are affected are 5.7.18 and earlier. Difficult to exploit 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 5.3 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H).
Vulnerabilidad en el componente MySQL Server en Oracle MySQL (subcomponente: Server: UDF). Las versiones compatibles que se han visto afectadas son la 8.54 y la 8.55. Una vulnerabilidad difícilmente explotable permite que un atacante con un bajo nivel de privilegios que tenga acceso a red por múltiples protocolos comprometa la seguridad de MySQL Server. Los ataques exitosos a esta vulnerabilidad pueden dar lugar a que el atacante consiga provocar el bloqueo o cierre repetido (DoS completo) de MySQL Server. CVSS 3.0 Base Score 5.3 (impactos en la disponibilidad). Vector CVSS: (CVSS:3.0/AV:N/AC:H/PR:L/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-mysql57-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.
