Xcode 5.0

• Git

  Available for: OS X Mountain Lion v10.8.4 or later

  Impact: An attacker with a privileged network position may intercept user credentials or other sensitive information

  Description: When using the imap-send command, git did not verify that the server hostname matched a domain name in the X.509 certificate, which allowed a man-in-the-middle attacker to spoof SSL servers via an arbitrary valid certificate. This issue was addressed by updating git to version 1.8.3.1.
