Qemu: improper ide controller reset can lead to mbr overwrite
概要
Qemu: improper ide controller reset can lead to mbr overwrite
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot.
