HP-UX bdf/df Buffer Overflow Vulnerabilities

There is a buffer overflow in the setuid utility /usr/bin/bdf that causes the program to exit with a memory fault when an argument to the -t option is supplied with more than 2415 characters (this number may vary - it has been demonstrated that 2599 characters are needed on an HP-UX 10.20 installation). It is not clear from the information that we have whether or not this is exploitable. It has been reported that the df(1M) program exhibits similar behaviour as well.
