It turns out that squashfs can end up being confused about # negative fragment lengths. # # The regular squashfs_read_data() does check for negative lengths, but # squashfs_read_metadata() did not, and the fragment size code just # blindly trusted the on-disk value. Fix both the fragment parsing and # the metadata reading code. # # Reported-by: Anatoly Trosinenko <anatoly.trosinenko@gmail.com> # Cc: Al Viro <viro@zeniv.linux.org.uk> # Cc: Phillip Lougher
