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")


Confirmed by HP: *NOT* a local root.

"The vulnerability could be exploited by a local, authorized user to
execute arbitrary code as a member of the 'mail' group."

Interesting enough to note that the bug is also present in HPUX (same
scope, again not a local root).

Netragard ppl should fix their advisory and web site...
