CVE-2024-0450: CPython <3.12.2 Vulnerable to ZipBombs via zipfile Module
CVE-2024-0450 Published on March 19, 2024
Quoted zip-bomb protection for zipfile
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.

Weakness Type
What is an Amplification Vulnerability?
Software that does not appropriately monitor or control resource consumption can lead to adverse system performance. This situation is amplified if the software allows malicious users or attackers to consume more resources than their access level permits. Exploiting such a weakness can lead to asymmetric resource consumption, aiding in amplification attacks against the system or the network.
CVE-2024-0450 has been classified to as an Amplification vulnerability or weakness.
