Hello,

I've just installed vulnerable package in my test-bed:

# uname -a
OSF1 alpha V5.1 2650 alpha
# pwd
/mnt/ALPHA/BASE
# setld -l . OSFCDEMAIL540
# ls -l /usr/dt/bin/dtmail
- -r-xr-sr-x   1 bin      mail     1212752 Oct 17  2002 /usr/dt/bin/dtmail
#

How is this a local root? (binary is setgid "mail" but not setuid "root")
