A malicious or compromised MySQL server can send a truncated packet and make the client read past the end of the packet buffer, which is undefined behaviour and can crash the process."

Un servidor MySQL malicioso o comprometido puede enviar un paquete truncado y hacer que el cliente lea más allá del final del búfer del paquete, lo que es un comportamiento indefinido y puede provocar la caída del proceso."
