Detailsinfo

A vulnerability was found in qemu (Virtualization Software). It has been declared as critical. Affected by this vulnerability is the function pciej_write of the component Power Management. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The pciej_write function in hw/acpi_piix4.c in the PIIX4 Power Management emulation in qemu-kvm does not check if a device is hotpluggable before unplugging the PCI-ISA bridge, which allows privileged guest users to cause a denial of service (guest crash) and possibly execute arbitrary code by sending a crafted value to the 0xae08 (PCI_EJ_BASE) I/O port, which leads to a use-after-free related to "active qemu timers."

The weakness was published 06/21/2012 (Website). The advisory is shared at lists.ubuntu.com. This vulnerability is known as CVE-2011-1751 since 04/19/2011. Access to the local network is required for this attack. The requirement for exploitation is a single authentication. Technical details are known, but no exploit is available.
