[Pkg-cups-devel] Bug#506702: cups: SSL compatibility problems w/FF3 (amongst others)

[Matthew Palmer]

Package: cups
Severity: important
Version: 1.3.8-1lenny2

Hi,

I've been having some problems creating a printer using the web interface in
the above CUPS version.  After some hunting, I've managed to find a very
nicely notated RHEL bug that describes the problem:

  https://bugzilla.redhat.com/show_bug.cgi?id=453610
  
Basically, when you attempt to submit a largish request over SSL using some
browsers (I've tested with FF3 and Epiphany 2.22.3, and both exhibit the
symptoms) the connection will hang, because CUPS has a bug in it's event
loop that gets in the way of the SSL connection.  "Largish requests" include
the POSTs to create a new printer, amongst other things (if you submit print
jobs over SSL, this bug could bite, depending on the client's SSL library).
  
The above bug points to a fix:

  http://cups.org/str.php?L2892

I've verified that the last patch in that ticket (str2892-1.3.patch) applies
cleanly and fixes the problem on my local amd64 system.

Please consider including this patch in lenny; it is practically impossible
to create a printer as it stands at the moment.

Thanks,
- Matt
