Security Update 2014-005

• Secure Transport

  Available for: OS X Mountain Lion v10.8.5, OS X Mavericks v10.9.5

  Impact: An attacker may be able to decrypt data protected by SSL

  Description: There are known attacks on the confidentiality of SSL 3.0 when a cipher suite uses a block cipher in CBC mode. An attacker could force the use of SSL 3.0, even when the server would support a better TLS version, by blocking TLS 1.0 and higher connection attempts. This issue was addressed by disabling CBC cipher suites when TLS connection attempts fail.
