Descriptions

The GetBlockHeadersMsg handler in the LES protocol implementation in Go Ethereum (aka geth) before 1.8.11 may lead to an access violation because of an integer signedness error for the array index, which allows attackers to launch a Denial of Service attack by sending a packet with a -1 query.Skip value. The vulnerable remote node would be crashed by such an attack immediately, aka the EPoD (Ethereum Packet of Death) issue.

El manipulador GetBlockHeadersMsg en la implementación del protocolo LES en Go Ethereum (también conocido como geth) en versiones anteriores a la1.8.11 puede conducir a una infracción de acceso debido a un error en la propiedad signedness de un número entero para el índice del array, lo que permite que los atacantes lancen un ataque de denegación de servicio (DoS) enviando un paquete con un valor -1 query.Skip. El nodo remoto vulnerable se cerraría de manera inesperada por dicho ataque inmediatamente, también conocido como vulnerabilidad EPoD (Ethereum Packet of Death).
