Descriptions

The JPXStream::init function in Poppler 0.78.0 and earlier doesn't check for negative values of stream length, leading to an Integer Overflow, thereby making it possible to allocate a large memory chunk on the heap, with a size controlled by an attacker, as demonstrated by pdftocairo.

La función JPXStream::init en Poppler versión 0.78.0 y anteriores, no comprueba los valores negativos de la longitud de la transmisión, lo que conlleva a un Desbordamiento de Enteros, y por lo tanto hace posible asignar una gran fragmento de memoria en la pila, con un tamaño controlado por un atacante, como es demostrado por pdftocairo.
