CVE-2012-2652 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-2652):
  The bdrv_open function in Qemu 1.0 does not properly handle the failure of
  the mkstemp function, when in snapshot node, which allows local users to
  overwrite or read arbitrary files via a symlink attack on an unspecified
  temporary file.

Since is marked as [ebuild] would be great if you mention the fixed version next time

The referenced commit that fixes this appears in the 1.1 release. 1.1.1-r1 is stable on amd64. We're waiting on x86 for bug #428476.
