Description

The version of Apple iTunes installed on the remote Mac OS X host is earlier than 10.5.1. As such, it uses an unsecured HTTP connection when checking for or retrieving software updates, which could allow a man-in-the-middle attacker to provide a Trojan horse update that appears to originate from Apple.
