CVE-2008-0928: Medium severity qemu vulnerability

Published Feb 20, 2008

Updated

Ian Jackson discovered that accesses beyond end of qemu emulated disk devices can result in accesses to emulator's virtual memory space accesses and thus can allow user with sufficient privilege in guest (root, as this would need modification to kernel's driver) to break out of VM.

Other sources

Qemu 0.9.1 and earlier does not perform range checks for block device read or write requests, which allows guest host users with root privileges to access arbitrary memory and escape the virtual machine.
