Overview
Affected versions of this package are vulnerable to Asymmetric Resource Consumption (Zip Bomb) in the zipfile module. An attacker can create a zip-bomb with a high compression ratio that exploits the zip format to overlap entries in the archive.
Workaround
Thee following check can be used before extracting a ZIP file.
# zipf is an open ZipFile
end_offset = zipf.start_dir
for zinfo in sorted(zipf.filelist,
key=lambda zinfo: zinfo.header_offset,
reverse=True):
if zinfo.header_offset + zinfo.compress_size > end_offset:
raise zipfile.BadZipFile('Overlapped entries')
end_offset = zinfo.header_offset
