Description

This security bulletin contains information about 1 security vulnerability.


1) Cryptographic issues (CVE-ID: CVE-2014-9742)

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.
