Multiple integer overflows in the (1) v9fs_xattr_read and (2) v9fs_xattr_write functions in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local guest OS administrators to cause a denial of service (QEMU process crash) via a crafted offset, which triggers an out-of-bounds access.

CVE-2016-9104 Qemu: 9pfs: integer overflow leading to OOB access
Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9
File System(9pfs) support, is vulnerable to an integer overflow issue. It
could occur by accessing xattributes values.
A privileged user inside guest could use this flaw to crash the Qemu process
instance resulting in DoS.
