F5 Networks BIG-IP : QEMU vulnerability (K41142448)

The version of F5 Networks BIG-IP installed on the remote host is prior to 17.1.3 / 17.5.1.1. It is, therefore, affected by a vulnerability as referenced in the K41142448 advisory. ethgetgsotype in net/eth.c in QEMU 4.2.1 allows guest OS users to trigger an assertion failure. A guest can crash th...

F5 Networks BIG-IP : QEMU vulnerability (K41301038)

The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the K41301038 advisory. - QEMU 5.0.0 has a use-after-free in hw/usb/hcd-xhci.c because the usbpacketmap return value is not checked...

QEMU: VNC: improper I/O watch removal in TLS handshake can lead to remote unauthenticated denial of service

A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QE...
