Detailed vulnerability description
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The OpenSSL address implementation in Socat 1.7.3.0 and 2.0.0-b8 does not use a prime number for the DH, which makes it easier for remote attackers to obtain the shared secret.
