===================================================
  Hello,

Quick Emulator(Qemu) built with the RTL8139 ethernet controller emulation support is vulnerable to an infinite loop issue. It could occur while transmitting packets in C+ mode of operation.


A privileged user inside guest could use this flaw to consume excessive CPU cycles on the host, resulting in DoS situation.
