ruby is vulnerable to symlink attack. A race condition flaw was found in the remove system entries method in the FileUtils module. If a local user ran a Ruby script that uses this method, a local attacker could use this flaw to delete arbitrary files and directories accessible to that user via a symbolic link attack.
