-Subject: [PATCH] rtp-recv: fix crash on empty UDP packets (CVE-2014-3970)
-
-On FIONREAD returning 0 bytes, we cannot return success, as the caller
-(rtpoll_work_cb in module-rtp-recv.c) would then try to
-pa_memblock_unref(chunk.memblock) and, because memblock is NULL, trigger
-an assertion.
-
-Also we have to read out the possible empty packet from the socket, so
-that the kernel doesn't tell us again and again about it.
