From: Kevin Day Date: Sat, 26 Feb 2022 16:50:26 +0000 (-0600) Subject: Security: The va_list has undefined behavior when passed into functions. X-Git-Tag: 0.5.8~5 X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=f8463f1275382c5de0e6154ff4e1190ba79404f6;p=fll Security: The va_list has undefined behavior when passed into functions. When the va_list is started using va_start(), the va_arg() must be called within the same function. This is a design problem with how va_list and its respective functions are implemented. The man pages directly document that passing an already started va_list to a function and then calling va_arg() is undefined. The va_list, being a macro, might also be a pointer. This makes passing it as a pointer (or with "const") risky. Due to the mentioned undefined states and risks, this is considered and treated as a security issue. Move the va_XXX() logic into a single function. This unfortunately means some functions have to be expanded out into the code and deleted. The code now, unfortunately, has more nested as a result of having to add more loops within the same function. The va_copy() macro is used and so the ap list state is no longer changed outside of the function. --- diff --git a/level_1/fl_print/c/print.c b/level_1/fl_print/c/print.c index 42c5032..e0ceb90 100644 --- a/level_1/fl_print/c/print.c +++ b/level_1/fl_print/c/print.c @@ -18,20 +18,7 @@ extern "C" { va_start(ap, stream);
