Description
In Apple OS X 10.10.4 and prior, the DYLD_PRINT_TO_FILE environment variable is used for redirecting logging data to a file instead of stderr. Due to a design error, this feature can be abused by a local attacker to write arbitrary files as root via restricted, SUID-root binaries.
Module options
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
