Vulnerability identifier: #VU46573
Vulnerability risk: Medium
Exploitation vector: Network
Exploit availability: No
Vendor: OpenSSL Software Foundation
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a timing flaw in the TLS specification. A remote attacker can compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite and eavesdrop on all encrypted communications sent over that TLS connection.
Note: The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections.
