Summary
zipfile: bzip2/LZMA/Zstandard members decompress without a max_length bound, defeating chunked-read memory limits
Details

When decompressing crafted zip files using the bzip/LZMA/Zstandard

compressions, Python could use an attacker-controlled size to

pre-allocate memory, possibly resulting in memory exhaustion.
