Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Inefficient Algorithmic Complexity (CVE-ID: CVE-2022-25881)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to regular expression denial of service that occurs when the server reads the cache policy from the request using this library. A remote unauthenticated attacker can send malicious request header values to the server and perform a denial of service attack.


2) Error Handling (CVE-ID: CVE-2023-23931)

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.
