**Name of the Vulnerable Software and Affected Versions** Botan versions prior to 1.10.8 Botan versions 1.11.x prior to 1.11.9 **Description** The issue concerns the Miller-Rabin primality check, which is used in cryptographic protection mechanisms. It improperly uses a single random base, making it easier for remote attackers to defeat these mechanisms via a DH group. **Recommendations** For versions prior to 1.10.8, update to version 1.10.8 or later. For versions 1.11.x prior to 1.11.9, update to version 1.11.9 or later.
