rh#1296567

Qemu emulator built with the IP checksum routines is vulnerable to an OOB read access issue. It could occur while computing checksum for TCP/UDP packets, as the function uses payload length from the packet without checking against the data buffer size.

A user inside guest could use this flaw to read excessive bytes or crash the Qemu process resulting in DoS.
