CVE-2008-1685
Description
From CVE.org
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)
Statement
The Red Hat Product Security is aware of this new gcc behavior and is currently working to determine what impact these changes will have on the source code processed by the compiler. These changes do not affect Red Hat Enterprise Linux 2, 3, 4, or 5.
