CVE-2008-1685
GCC Integer Overflow and Cast Vulnerability in Pointer Arithmetic
Description
gcc 4.2.0 through 4.3.0 in GNU Compiler Collection, when casts are not used, considers the sum of a pointer and an int to be greater than or equal to the pointer, which might lead to removal of length testing code that was intended as a protection mechanism against integer overflow and buffer overflow attacks, and provide no diagnostic message about this removal. NOTE: the vendor has determined that this compiler behavior is correct according to section 6.5.6 of the C99 standard (aka ISO/IEC 9899:1999)

Action Type Old Value New Value Removed Translation gcc de 4.2.0 a 4.3.0 en GNU Compiler Collection, cuando no se usan casts, considera que la suma de un puntero y un entero es mayor o igual que el puntero, lo que podría eliminar el código de comprobación de longitud que estaba previsto como un mecanismo de protección contra desbordamientos de enteros y ataques de desbordamiento de búfer.
