Security vulnerability in OpenSSL
DESCRIPTION: SSL/TLS MITM vulnerability
An attacker using a carefully crafted handshake can force the use of weak keying material in OpenSSL SSL/TLS clients and servers. This can be exploited by a Man-in-the-middle (MITM) attack where the attacker can decrypt and modify traffic from the attacked client and server.
The attack can only be performed between a vulnerable client *and* server. OpenSSL clients are vulnerable in all versions of OpenSSL. SVC and Storwize systems use OpenSSL server functionality and some versions are vulnerable (see below).
