Descriptions
QEMU (aka Quick Emulator) built to use 'address_space_translate' to map an address to a MemoryRegionSection is vulnerable to an OOB r/w access issue. It could occur while doing pci_dma_read/write calls. Affects QEMU versions >= 1.6.0 and <= 2.3.1. A privileged user inside guest could use this flaw to crash the guest instance resulting in DoS.
QEMU (también conocido como Quick Emulator) construido para usar 'address_space_translate' para asignar una dirección a una MemoryRegionSection es vulnerable a un problema de acceso OOB r/w. Podría ocurrir mientras se hacen llamadas pci_dma_read/write. Afecta las versiones de QEMU >= 1.6.0 and <= 2.3.1. Un usuario privilegiado dentro del huésped podría usar esta falla para bloquear la instancia del huésped resultando en DoS.
An out-of-bounds flaw was found in the QEMU emulator built using 'address_space_translate' to map an address to a MemoryRegionSection. The flaw could occur while doing pci_dma_read/write calls, resulting in an out-of-bounds read-write access error. A privileged user inside a guest could use this flaw to crash the guest instance (denial of service).
