CVE-2016-5238
First published: Thu Jun 02 2016(Updated: )
Quick Emulator(Qemu) built with the ESP/NCR53C9x controller emulation support is vulnerable to an OOB write access issue. The controller uses 16-byte FIFO buffer for command and information transfer. The OOB write occurs while reading from information transfer buffer via non-DMA mode in routine get_cmd(). A privileged user inside guest could use this flaw to crash the Qemu process resulting in DoS.
