Oracle VM VirtualBox - 'virtio-net' Guest-to-Host Out-of-Bounds Write

Source: https://bugs.chromium.org/p/project-zero/issues/detail?id=1136 This is a vulnerability that affects VirtualBox VMs that use a virtio network adapter which is a non-standard configuration. It permits the guest kernel to write up to 4GB of controlled data out of bounds in the trusted userla...

VirtualBox Guest-To-Host Out-Of-Bounds Write Exploit

Exploit for multiple platform in category dos / poc VirtualBox: guest-to-host out-of-bounds write via virtio-net CVE-2017-3575 This is a vulnerability that affects VirtualBox VMs that use a virtio network adapter which is a non-standard configuration. It permits the guest kernel to write up to 4G...

The vulnerability of the QEMU hardware emulation software allows a malicious actor to trigger a failure in the host operating system’s maintenance or execute arbitrary code.

The QEMU software contains a vulnerability related to buffer overflows when the virtionethandlemac function is called to update the MAC address table of the guest operating system. This allows the user of the guest operating system to compromise the integrity of the dynamic memory of the host...
