-Subject: [PATCH] slirp: check pkt_len before reading protocol header
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-While processing ARP/NCSI packets in 'arp_input' or 'ncsi_input'
-routines, ensure that pkt_len is large enough to accommodate the
-respective protocol headers, lest it should do an OOB access.
-Add check to avoid it.
-
-CVE-2020-29129 CVE-2020-29130
- QEMU: slirp: out-of-bounds access while processing ARP/NCSI packets
