Decoding SPDX, CycloneDX and syft-json rebuilt nested archive chains from whatever the document said, with no checks on entry names, depth or length. A small crafted document could forge archive boundaries or cost memory quadratic in its size (a 3 MB SPDX allocated ~14 GB). - decoders now hold names to the scan's `EntryName` rules, and chains to `MaxDepth` (16) and PATH_MAX in length - a file within a refused chain is dropped, rather than moved to a top-level path or merged into its outer archive - the scan holds itself to the same bounds, so its SBOMs always decode back: a configured `nested-archive-max-depth` past 16 stops at 16, and an entry whose chain would be too long is skipped and the archive reported as truncated Signed-off-by: Alex Goodman <wagoodman@users.noreply.github.com>
