[U-Boot] [PATCH 0/6] handle compression buffer overflows

[Kees Cook]

This series fixes gzip, lzma, and lzo to not overflow when writing
to output buffers. Without this, it might be possible for untrusted
compressed input to overflow the buffers used to hold the decompressed
image.

To catch these conditions, I added a series of compression tests available
in the sandbox build. Without the fixes in patches 3, 4, and 5, the
overflows are visible.

Thanks,
