Detailed vulnerability description
The vulnerability allows a remote attacker to force SSLv3 usage.
When OpenSSL is configured with "no-ssl3" as a build option, servers could accept and complete a SSL 3.0 handshake, and clients could be configured to send them. A remote attacker can force SSLv3 usage and perfom a variety of attacks against SSLv3 protocol
Successful exploitation of the vulnerability may allow an attacker to obtain potentially sensitive information.
