Description
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The Miller-Rabin primality check in Botan before 1.10.8 and 1.11.x before 1.11.9 improperly uses a single random base, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a DH group.
