Description
This security bulletin contains information about 2 secuirty vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2014-3566)
The vulnerability allows a remote attacker to perform MitM attack.The vulnerability exists due to usage of insecure SSLv3 protocol in OpenSSL. A remote attacker can force the current connection between user and server to be downgraded to SSLv3 protocol and then use padding-oracle attack on Cypher-block chaining (CBC) mode to decrypt encrypted communication.
Successful exploitation of the vulnerability may allow an attacker to read encrypted communications in clear text.
Note: The vulnerability is known as POODLE.
2) Forced SSLv3 support (CVE-ID: CVE-2014-3568)
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.
