NVD Description

Note: Versions mentioned in the description apply only to the upstream avahi package and not the avahi package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. In 0.9-rc2 and earlier, an unprivileged local users can crash avahi-daemon (with wide-area disabled) by creating record browsers with the AVAHI_LOOKUP_USE_WIDE_AREA flag set via D-Bus. This can be done by either calling the RecordBrowserNew method directly or creating hostname/address/service resolvers/browsers that create those browsers internally themselves.
