The OS X command line developer tools include an old version of the Git source-code management system that exposes Mac users to remote code-execution attacks. “If you rely on machines like this, I am truly sorry,” said systems administration expert Rachel Kroll. “I feel for you.”
The Git client allows developers to interact with source code repositories. It is not installed by default on Mac OS X, but it is included in the Command Line Tools package for Xcode, Apple’s integrated development environment (IDE).
