Description Adam Mariš 2016-04-22 10:19:47 UTC 
Quick Emulator(Qemu) built with the AMD PC-Net II emulator support is vulnerable to an infinite loop issue. It could occur while transmitting packets via pcnet_transmit().

A privileged user/process inside guest could use this issue to crash the Qemu process on the host leading to DoS.
