Existe una vulnerabilidad de desbordamiento de búfer en Pev 0.81 a través de la función pe_exports de exports.c. El array offsets_to_Names se asigna dinámicamente en la pila utilizando exp->NumberOfFunctions como su tamaño. Sin embargo, el bucle utiliza exp->NumberOfNames para iterar sobre él y establecer el valor de sus componentes. Por tanto, el código del bucle asume que exp->NumberOfFunctions es mayor que ordinal en cada iteración. Esto puede conducir a la ejecución arbitraria de código.

Therefore, the loop code assumes that exp->NumberOfFunctions is greater than ordinal at each iteration. This can lead to arbitrary code execution."
