[tbox-l] wu-ftpd 'ls' bug

[Aaron W M. <aar...@gm...>]

Hello all,

This was also posted earlier this year.  There is a bug with wu-ftpd
on AIX when you run 'ls' with any parameters.  ('ls' with no
parameters works fine)  eg....

$ ftp localhost
Connected to loopback.
220-
Name (localhost:foo):
331 Password required for foo.
Password:
230 User foo logged in.  Access restrictions apply.
ftp> ls -l
200 PORT command successful.
550 /bin/ls -l: Not enough space.

A quick search on Google shows that others have been having this issue
for quite a while with no success:  Reference:

A post on a bugtrac mailing list seems to indicate that it might have
something to do with a couple of the most recent vulnerability patches
for wu-ftpd.  Reference:

Also, here is a truss trace of the above transacation where I run 'ls -l':

Finally, my pertinent system info:
AIX 5300-05
wu-ftpd-2.6.2-6

Any help would be most appreciated.
