CVE-2015-8666 [HIGH] CWE-122 Qemu: acpi: heap based buffer overrun during VM migration
Qemu: acpi: heap based buffer overrun during VM migration
Heap-based buffer overflow in QEMU, when built with the Q35-chipset-based PC system emulator.
A heap-based buffer overflow flaw was discovered in the QEMU emulator built with the Q35-chipset-based PC system emulator. During VM-guest migration, more data (8 bytes) is moved than the allocated memory area. A privileged guest user could use this flaw to corrupt the VM guest image, which could potentially lead to a denial of service.
Statement: This issue does not affect the versions of the kvm and xen packages as shipped with Red Hat Enterprise Linux 5.
This issue does not affect the versions of the qemu-kvm packages as shipped with Red Hat Enterprise Linux 6, and the Red Hat Enterprise Linux 6 based versions of qemu-kvm-rhev package

CVE-2015-8666 Qemu: acpi: heap based buffer overrun during VM migration
Qemu emulator built with the Q35 chipset based pc system emulator is vulnerable to a heap based buffer overflow. It occurs during VM guest migration, as more(8 bytes) data is moved than allocated memory area.
A privileged guest user could use this issue to corrupt the VM guest image, potentially leading to a DoS. This issue affects q35 machine types.
