Several vulnerabilities have been discovered in the QEMU processor

following problems:

CVE-2008-0928

Ian Jackson discovered that range checks of file operations on
emulated disk devices were insufficiently enforced.

removable media could lead to the disclosure of files in the
host system.

A buffer overflow has been found in the emulation of the Cirrus
graphics adaptor.


For the old stable distribution (etch), these problems have been fixed in
version 0.8.2-4etch3.
