Descriptions

There is a pointer double free vulnerability in some versions of CloudEngine 5800, CloudEngine 6800, CloudEngine 7800 and CloudEngine 12800. When a function is called, the same memory pointer is copied to two functional modules. Attackers can exploit this vulnerability by performing a malicious operation to cause the pointer double free. This may lead to module crash, compromising normal service.

Se presenta una vulnerabilidad de puntero doble liberación en algunas versiones de CloudEngine 5800, CloudEngine 6800, CloudEngine 7800 y CloudEngine 12800. Cuando es llamada una función, el mismo puntero de memoria es copiada en dos módulos funcionales. Unos atacantes pueden explotar esta vulnerabilidad al llevar a cabo una operación maliciosa para causar el puntero doblemente liberado. Esto puede conllevar a un bloqueo del módulo, comprometiendo el servicio normal
