Please unblock package linux-igd.
The upload fixes one severity Important use-after-free-bug:
#499827 linux-igd: upnpd segfault error 4 in libc-2.7.so
and also applies the Wheezy hardening release goal as this package meets
the category "All daemons and libraries accessible from the network".
linux-igd (1.0+cvs20070630-4) unstable; urgency=low
* Apply patch 16 from Rob Lesley to fix use-after-free (Closes: #499827)
* Apply hardening in line with Wheezy release goal, as we are a daemon
and handle unsanitised input from the net. Update *FLAGS in line
with this to be supplied by dh_buildflags.
* Update Policy to 3.9.3 (no change to package).
On a review of the debdiff I can see that there are two additional changes
in the packaging but they should not affect the build or the resulting
binary so I hope the upload can still be accepted. Please let me know
if you would rather I re-upload anyway:
* the versioned B-D on libupnp4-dev is tightened but still matches the
version in Wheezy (before freeze I was considering updating linux-igd
to use a newer libupnp, but that is too invasive a change so I reverted
it for this upload, but it left this one change in debian/control).
* a change to the comments in debian/watch (this was a Lintian warning
I was also working on at the time)
