    Changed Description A heap-based buffer overflow flaw was discovered in the way QEMU's AMD PC-Net II Ethernet Controller emulation received certain packets in loopback mode. A privileged user (with the CAP_SYS_RAWIO capability) inside a guest could use this flaw to crash the host QEMU process (resulting in denial of service) or, potentially, execute arbitrary code with privileges of the host QEMU process.
