The nargs value can overflow when doing allocations, allowing arbitrary
memory writes via format strings, bypassing _FORTIFY_SOURCE:
http://www.phrack.org/issues.html?issue=67&id=9
This checks for nargs overflow and possibly allocates from heap instead of
stack, and adds a regression test for the situation.
I have FSF assignment via Google. (Sent from @outflux since that's how I'm
subscribed here, but CL shows @chromium.org as part of my Google work.)
This version disables the useless test on non-32-bit platforms.
2012-02-16 Kees Cook <keescook@chromium.org>
[BZ #13656]
* stdio-common/vfprintf.c (vfprintf): Check for nargs overflow and
possibly allocate from heap instead of stack.
* stdio-common/bug-vfprintf-nargs.c: New file.
* stdio-common/Makefile (tests): Add nargs overflow test.
