## Overview

Apache WSS4J accepted attacker-controlled derived-key lengths and offsets without adequate bounds. This could permit cryptographically weak keys or excessive CPU and memory consumption when processing crafted WS-Security messages. The fixes enforce a minimum key length of 16 bytes, a maximum length of 512 bytes, and a maximum offset of 4096 bytes.
Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.

## Affected

- `wss4j < 2.4.4`
- `wss4j >= 3.0.0, < 3.0.6`
- `wss4j >= 4.0.0, < 4.0.2`

## Remediation

Upgrade past the affected range:

- `wss4j 4.0.2`
