Dear Simon Glass,
In message 1316799532-20761-1-git-send-email-sjg@chromium.org you wrote:
The printf family of functions in U-Boot cannot deal with a situation where the caller provides a buffer which turns out to be too small for the format string. This can result in buffer overflows, stack overflows and other bad behavior.
This patch series tidies this up in the common vsprintf.c code, and also some network code (as an example of where this might lead).
What's the impact of this patch set on the memory footprint of typical configurations?
Best regards,
Wolfgang Denk
