-Subject: [PATCH] sysdeps-unix: On MSG_CTRUNC, close the fds we did receive
-
-MSG_CTRUNC indicates that we have received fewer fds that we should
-have done because the buffer was too small, but we were treating it
-as though it indicated that we received *no* fds. If we received any,
-we still have to make sure we close them, otherwise they will be leaked.
-
-On the system bus, if an attacker can induce us to leak fds in this
-way, that's a local denial of service via resource exhaustion.

-Fixes: dbus#294
-Fixes: CVE-2020-12049
