An issue was discovered in Wind River VxWorks 7. The memory allocator has a possible integer overflow in calculating a memory block's size to be allocated by calloc(). As a result, the actual memory allocated is smaller than the buffer size specified by the arguments, leading to memory corruption.

Como resultado, la memoria actual asignada es menor que el tamaño del búfer especificado por los argumentos, conllevando a una corrupción de la memoria
