+Subject: [PATCH] slirp: fix clearing ifq_so from pending packets
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The if_fastq and if_batchq contain not only packets, but queues of packets
+for the same socket. When sofree frees a socket, it thus has to clear ifq_so
+from all the packets from the queues, not only the first.

+From: Prasad J Pandit <address@hidden>
+
+While loading kernel via multiboot-v1 image, (flags & 0x00010000)
+indicates that multiboot header contains valid addresses to load
+the kernel image. These addresses are used to compute kernel
+size and kernel text offset in the OS image. Validate these
+address values to avoid an OOB access issue.
+
+This is CVE-2017-14167.
