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)

Affected products

GNU GCC: 4.2.0, 4.2.1, 4.2.2, 4.2.3, 4.2.4, 4.3.0
