Descriptions
The process_tx_desc function in hw/net/e1000.c in QEMU before 2.4.0.1 does not properly process transmit descriptor data when sending a network packet, which allows attackers to cause a denial of service (infinite loop and guest crash) via unspecified vectors.
La función process_tx_desc en el archivo hw/net/e1000.c en QEMU versiones anteriores a 2.4.0.1, no procesa apropiadamente los datos del descriptor de transmisión cuando se envía un paquete de red, lo que permite a atacantes causar una denegación de servicio (bucle infinito y bloqueo de invitado) por medio de vectores no especificados.
Lian Yihan discovered that QEMU incorrectly handled certain payload messages in the VNC display driver. A malicious guest could use this issue to cause the QEMU process to hang, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Qinghao Tang discovered that QEMU incorrectly handled receiving certain packets in the NE2000 network driver. A malicious guest could use this issue to cause the QEMU process to hang, resulting in a denial of service. Various other issues were also addressed.
