Описание
Heap-based buffer overflow in the IDE subsystem in QEMU, as used in Xen 4.5.x and earlier, when the container has a CDROM drive enabled, allows local guest users to execute arbitrary code on the host via unspecified ATAPI commands.
A heap buffer overflow flaw was found in the way QEMU's IDE subsystem handled I/O buffer access while processing certain ATAPI commands. A privileged guest user in a guest with the CDROM drive enabled could potentially use this flaw to execute arbitrary code on the host with the privileges of the host's QEMU process corresponding to the guest.
Отчет
This issue does not affect the versions of the kvm and xen packages as shipped with Red Hat Enterprise Linux 5, the versions of the qemu-kvm packages as shipped with Red Hat Enterprise Linux 6 and the Red Hat Enterprise Linux 6 based qemu-kvm-rhev packages as shipped with Red Hat Enterprise Virtualization 3, because they did not backport the upstream commit that introduced this issue. This issue does affect the versions of qemu-kvm packages as shipped with Red Hat Enterprise Linux 7 and versions of Red Hat Enterprise Linux 7 based qemu-kvm-rhev packages as shipped with Red Hat Enterprise Virtualization 3. Future updates for the respective releases will address this flaw.
