While on the subject of UPS software exploits, I have run across another one.

MGE UPS's (http://www.mgeups.com/) Solution Pac software firstly installs as
mode 666/777, which, although easy to correct, should be fixed.

Next, the programs, when starting up, create lock files in /tmp:
COM_init.lock
MON_init.lock

These files are created with mode 666, and ignore the current umask.
I sent a message to MGEUPS 4 months ago with this information, but have had no
reply.

If you are running the software, you may want to clear /tmp at boot, at least
for the lock files.  Otherwise any user can turn any file on the system to 0
bytes.
