rh#1457832 A vulnerability was found in perl File-Path. In the rmtree() and remove_tree() functions, the chmod()logic to make directories traversable can be abused to set the mode on an attacker-chosen file to an attacker-chosen value. This is due to the time-of-check-to-time-of-use (TOCTTOU) race condition between the stat() that decides the inode is a directory and the chmod() that tries to make it user-rwx.
