Descriptions

Info-ZIP UnZip 6.0 has a buffer overflow in list.c, when a ZIP archive has a crafted relationship between the compressed-size value and the uncompressed-size value, because a buffer size is 10 and is supposed to be 12.

Info-ZIP UnZip 6.0 tiene un desbordamiento de búfer en list.c, cuando un archivo ZIP tiene una relación manipulada entre el valor de tamaño comprimido y el no comprimido. Esto se debe a que el tamaño de búfer es 10 y se supone que es 12.
