[PATCH] initramfs: handle unrecognised decompressor when unpacking
The unpack routine fails to handle the decompress_method() returning unrecognised decompressor (compress_name == NULL). This results in the routine looping eventually oopsing on an out of bounds memory access. Note this bug is usually hidden, only triggering on trailing junk after one or more correct compress... 23 Apr 2010 21:10

[PATCH 4/4] squashfs: fix potential buffer over-run on 4K block file systems
Sizing the buffer based on block size is incorrect, leading to a potential buffer over-run on 4K block size file systems (because the metadata block size is always 8K).
