Descriptions

Off-by-one error in the pci_read function in the ACPI PCI hotplug interface (hw/acpi/pcihp.c) in QEMU allows local guest users to obtain sensitive information and have other unspecified impact related to a crafted PCI device that triggers memory corruption.

Error de superación de límite (off-by-one) en la función pci_read en ACPI PCI interfaz hotplug (hw/acpi/pcihp.c) en QEMU permite a usuarios locales invitados obtener información sensible y tener otro impacto no especificado relacionado con un dispositivo PCI manipulado que provoca daños en la memoria.

Laszlo Ersek discovered that QEMU incorrectly handled memory in the vga device. A malicious guest could possibly use this issue to read arbitrary host memory. This issue only affected Ubuntu 14.04 LTS and Ubuntu 14.10. Xavier Mehrenberger and Stephane Duverger discovered that QEMU incorrectly handled certain udp packets when using guest networking. A malicious guest could possibly use this issue to cause a denial of service. Various other issues were also addressed.
