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...
