Hello,Quick emulator(Qemu) built with the virtio framework is vulnerable to an infinite loop issue. It could occur if the guest was to set the I/O descriptor buffer length to be zero. A privileged user inside guest could use this flaw to potentially crash the Qemu instance on the host resulting in DoS.
Upstream fix: ------------- -> https://lists.gnu.org/archive/html/qemu-devel/2016-07/msg06246.html This issue was discovered by Li Qiang of 360.cn Inc. Thank you. -- Prasad J Pandit / Red Hat Product Security Team 47AF CE69 3A90 54AA 9045 1053 DD13 3D32 FE5B 041F
