"http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-7575 The TLS
protocol could allow weaker than expected security caused by a
collision attack when using the MD5 hash function for signing a
ServerKeyExchange message during a TLS handshake. An attacker could
exploit this vulnerability using man-in-the-middle techniques to
impersonate a TLS server and obtain credentials. IBM AIX does not
require the newest version of TLS by default which could allow a
remote attacker to obtain sensitive information using man in the
middle techniques.");
