Descriptions

On all 7.x versions (fixed in 8.0.0), when set up for auto failover, a BIG-IQ Data Collection Device (DCD) cluster member that receives an undisclosed message may cause the corosync process to abort. This behavior may lead to a denial-of-service (DoS) and impact the stability of a BIG-IQ high availability (HA) cluster. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.

En todas las versiones 7.x (corregidas en 8.0.0), cuando se configura para la conmutación automática por error, un miembro del clúster BIG-IQ Data Collection Device (DCD) que recibe un mensaje no revelado puede hacer que el proceso de corosync se anule. Este comportamiento puede conducir a una denegación de servicio (DoS) y afectar la estabilidad de un clúster de alta disponibilidad (HA) de BIG-IQ. Nota: No se evalúan las versiones de software que han alcanzado End of Software Development (EoSD).
