ciphers. A man-in-the-middle attacker could have injected invalid
data, causing the connection to close but revealing some information
about the previous data. If the same connection was attempted
repeatedly the attacker may eventually have been able to decrypt the
data being sent, such as a password. This issue was addressed by
enabling TLS 1.2.

CVE-ID
CVE-2013-4073

Security
Impact:  Support for X.509 certificates with MD5 hashes may expose
users to spoofing and information disclosure as attacks improve
Description:  Certificates signed using the MD5 hash algorithm were
accepted by OS X. This algorithm has known cryptographic weaknesses.
Further research or a misconfigured certificate authority could have
allowed the creation of X.509 certificates with attacker controlled
values that would have been trusted by the system. This would have
