Package: cupsys
Version: 1.1.23-15

I have cupsd.conf configured to use encryption IfRequested.

Adding printer kalle always works just fine without encryption

# lpadmin -p Kalle -P ~lpetos/xr_dc440.ppd -v ipp://kalle/

When using encryption it does not work most of the time, repeating command
several times may get it to work eventually.

# lpadmin -p Kalle -P xr_dc440.ppd -v ipp://kalle/
<Just hangs - no response, several minutes>
<CTRL-C>

Traces

# strace -o lpadmin-E.log lpadmin -E -p Kalle -P xr_dc440.ppd -v ipp://kalle/
<CTRL-C>

See attached logfiles. The lpadmin-E-ok.log is from a execution that
actually works even with encryption. By filtering one can see intrerresting
similarities and that a SIGPIPE is received when it goes bad.

# egrep "send|recv|connect|accept|close" lpadmin-E.log  | less
# egrep "send|recv|connect|accept|close" lpadmin-E-ok.log  | less

The cups error_log show that something unexpected is received
 "Bad request line "^W^C^A" from localhost!"
Several times, until the last one when it actually succeeds.

If the fault is a buffer overrun in the server then I guess it is a security
related bug.

Dear bug submitter,

This bug was reported against a very old version of cups (older than
in the current stable Debian version "Etch"). About a year ago,
Martin-Eric Racine asked for feedback whether the bug still applied to
the current Debian Etch version, but we did not get any feedback. In
order to not keep around old, hardware-specific, and inactive bugs
around forever, I close this bug now.

Please report back if you still experience the problem with the
current version in Etch; if you can test Lenny/unstable, that would be
highly appreciated, of course. I will reopen this bug then.

Thank you for your report!

Martin
