An issue was found in the CPython `zipfile` module affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior. The zipfile module is vulnerable to “quoted-overlap” zip-bombs which exploit the zip format to create a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile module reject zip archives which overlap entries in the archive. A flaw was found in the Python/CPython 'zipfile' that can allow a zip-bomb type of attack. An attacker may craft a zip file format, leading to a Denial of Service when processed.
