CVE-2008-1685: GNU Gcc

Medium severity, CVSS 6.8. EPSS: 1.3% chance of exploitation in the next 30 days.

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: version 4.2.0 only; version 4.2.1 only; version 4.2.2 only; version 4.2.3 only; version 4.2.4 only; version 4.3.0 only
