An infinite loop issue was found in the e1000 NIC emulator of the QEMU. It occurs while processing transmit (tx) descriptors in process_tx_desc, if various descriptor fields are initialised with invalid values. A guest may use this flaw to consume CPU cycles on the host resulting in a denial of service (DoS) scenario.
