Descriptions
Exim 4 before 4.94.2 allows Integer Overflow to Buffer Overflow because get_stdinput allows unbounded reads that are accompanied by unbounded increases in a certain size variable. NOTE: exploitation may be impractical because of the execution time needed to overflow (multiple days).
Exim 4 versiones anteriores a 4.94.2 permite el Desbordamiento de Enteros para un Desbordamiento de Búfer porque la función get_stdinput permite lecturas ilimitadas que van acompañadas de aumentos ilimitados en una determinada variable de tamaño. NOTA: la explotación puede no ser práctica debido al tiempo de ejecución necesario para desbordar (múltiples días)
