Bug description:
Binary package hint: lirc

Hi!

It has taken me a while to get to the bottom of why the remote IR control sensor on my Hauppauge PVR 350 TV card was failing to work.  on linux-image-2.6.28 there was no information coming in at all.  irw failed to give any keypress output, and irrecord failed to sense anything, timing out because it could not find a repeat event.

Tried IR sensor cables in my Hauppauge HVR4000, and they both work, so its not a faulty sensor.  Both my Hauppauge remotes work via the HVR4000 IR port as well.

Source package: lirc, version 0.8.4a; linux-image-2.6.28-generic
System: Mythbuntu jaunty 9.04, linux-image-2.6.28-14-generic
Policy:  Universe repository
Security: buffer length mishandling in lirc_dev module, which is part of standard Ubuntu kernel
Solution: create new package from upstream lirc CVS

Looks like the problem is in lirc_dev module with buffer size miscalculations (this could be a security problem with a possible buffer overrun) as per Fedora bug #507047:

https://bugzilla.redhat.com/show_bug.cgi?id=507047

To compile LIRC source though to test this it will take me a day or so to get a Jaunty i386 devel envionment working - the PVR 350 is in a diskless i386 LTSP client and my master server is amd64.
