Hi,
I'd like to make a stable upload for avahi.
The changelog reads:
avahi (0.8-5+deb11u1) bullseye; urgency=medium
[ Simon McVittie ]
* Add patch to fix display of URLs containing '&' in avahi-discover.
Otherwise, a TXT entry containing a URL with '&' will cause an error.
[ Michael Biebl ]
* Do not disable timeout cleanup on watch cleanup.
This was causing timeouts to never be removed from the linked list that
tracks them, resulting in both memory and CPU usage to grow larger over
time. Thanks to Gustavo Noronha Silva. (Closes: #993051)
* Fix NULL pointer crashes when trying to resolve badly-formatted hostnames.
Fixes a local DoS in avahi-daemon that can be triggered by trying to
resolve badly-formatted hostnames on the /run/avahi-daemon/socket
interface. (CVE-2021-3502, Closes: #986018)
Those are 3 cherry-picks from changes that are already part of 0.8-6
from unstable/testing.
I consider the regression potential low, as those fixes have been in
unstable/testing for a long time.
Regards,
Michael

+Subject: Fix NULL pointer crashes from #175
+
+avahi-daemon is crashing when running "ping .local".
+The crash is due to failing assertion from NULL pointer.
+Add missing NULL pointer checks to fix it.
+
+Introduced in #175 - merge commit 8f75a045709a780c8cf92a6a21e9d35b593bdecd
+
+(cherry picked from commit 9d31939e55280a733d930b15ac9e4dda4497680c)
