Pluggable Authentication Modules (PAM) is vulnerable to remote code execution (RCE). It was discovered that the pam_xauth module did not verify the return values of the setuid() and setgid() system calls. A local, unprivileged user could use this flaw to execute the xauth command with root privileges and make it read an arbitrary input file.
