1) Error Handling

EUVDB-ID: #VU72036

Risk: Low

CVSSv3.1: 2 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-23931

Exploit availability: No

Description

The vulnerability allows an attacker to misuse Python API.

The vulnerability exists due to a soundness bug within the Cipher.update_into function, which can allow immutable objects (such as bytes) to be mutated. A malicious programmer can misuse Python API to introduce unexpected behavior into the application.

Mitigation

Update the affected package python-cryptography to the latest version.
