A NULL pointer dereference in the illumos Network Auto-Magic daemon (nwamd) allows a local user to crash the daemon. nwamd_door_switch() in usr/src/cmd/cmd-inet/lib/nwamd/door_if.c writes to the caller's request structure before checking that a request was supplied, and before checking the caller's credentials. Because the nwamd door at /etc/svc/volatile/nwam/nwam_door is accessible to all local users, an unprivileged user can issue a door_call() with no argument data to crash nwamd; repeated calls place the svc:/network/physical:nwam service into maintenance, stopping automatic network configuration. nwamd runs only when svc:/network/physical:nwam is enabled, which is not the default. The flaw has existed since 2010 (illumos-gate commit 6ba597c5), and affects any illumos distribution prior to illumos-gate commit 0f1064d9.
