Title:	OpenSSL: Raccoon Attack (CVE-2020-1968) - Linux
Summary:	OpenSSL is prone to Racoon attacks.
Description:	Summary: OpenSSL is prone to Racoon attacks. Vulnerability Insight: The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent over that TLS connection. The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections. Note that this issue only impacts DH ciphersuites and not ECDH ciphersuites. Vulnerability Impact: An attacker may eavesdrop on encrypted communications sent over a TLS connection. Affected Software/OS: OpenSSL versions 1.0.2 - 1.0.2v and probably 1.1.0. Solution: Update to version 1.0.2w, 1.1.1 or later. CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:N/A:N
