"The version of Apple Xcode installed on the remote Mac OS X host is prior to 7.3.1. It is, therefore, affected by
multiple remote code execution vulnerabilities in the bundled version of Git due to overflow conditions in the
path_name() function in revision.c that are triggered when pushing or cloning a repository with a large filename or
containing a large number of nested trees. A remote attacker can exploit these issues to cause a heap-based buffer
overflow, resulting in the execution of arbitrary code.");
