Arista EOS before 4.20.2F allows remote BGP peers to cause a denial of service (Rib agent restart) via a malformed path attribute in an UPDATE message.

Arista EOS through 4.21.0F allows a crash because 802.1x authentication is mishandled.

qemu: net: e1000: infinite loop issue

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.

kernel: qemu buffer overflow in virtio-serial

Buffer overflow in the send_control_msg function in hw/char/virtio-serial-bus.c in QEMU before 2.4.0 allows guest users to cause a denial of service (QEMU process crash) via a crafted virtio control message.

qemu: Infinite loop in ne2000_receive() function

The ne2000_receive function in hw/net/ne2000.c in QEMU before 2.4.0.1 allows attackers to cause a denial of service (infinite loop and instance crash) or possibly execute arbitrary code via vectors related to receiving packets.

qemu-kvm: Integer overflow in vnc_client_read() and protocol_client_msg()

Integer overflow in the VNC display driver in QEMU before 2.1.0 allows attachers to cause a denial of service (process crash) via a CLIENT_CUT_TEXT message, which triggers an infinite loop.
