CVE-2011-2527 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-2527):
  The change_process_uid function in os-posix.c in Qemu 0.14.0 and earlier
  does not properly drop group privileges when the -runas option is used,
  which allows local guest users to access restricted files on the host.

This affects current app-emulation/qemu-user ebuilds in the tree (but not app-emulation/qemu).

qemu-user has been removed from the tree as its functionality has been superseded by the combined app-emulation/qemu package.  if you find the qemu package does not support something that the qemu-user package did, please file a new bug explicitly detailing things so we can get it added.
