Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. char str[100]; data/floatbg-1.0/floatbg.c:270:2: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).

Use sprintf_s, snprintf, or vsnprintf. Risk is low because the source has a constant maximum length. sprintf(cmd,"gconftool --type string --set /desktop/gnome/background/primary_color \"#%04x%04x%04x\"", data/floatbg-1.0/floatbg.c:277:9: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).
