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. Upstream patch: --------------- -> https://lists.gnu.org/archive/html/qemu-devel/2016-03/msg00671.html Reference: ---------- -> https://bugzilla.redhat.com/show_bug.cgi?id=1296567 This issue was discovered by Ling Liu of Qihoo 360 Inc.
