    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.(CVE-2025-68276)
