Description
This Metasploit module exploits a vulnerability in the FreeBSD run-time link-editor (rtld). The rtld unsetenv() function fails to remove LD_* environment variables if __findenv() fails. This can be abused to load arbitrary shared objects using LD_PRELOAD, resulting in privileged code execution.
