Doc Text:
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).

Description Adam Mariš 2016-01-21 11:51:13 EST
Qemu 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 & <= 2.3.1.

A privileged user inside guest could use this flaw to crash the guest instance resulting in DoS.
