Race Chmod

Usage of the `chmod` function call hints at a potential Time Of Check Time Of Use (TOCTOU) vulnerability. An attacker may be able to modify the file being specified by the `chmod` function prior to the `chmod` function being called. Since `chmod` will resolve symbolic links, an attacker may be able to exploit this fact to have files outside of their control
