CVE ID : CVE-2008-0928 CVE-2008-4539 CVE-2008-1945

Several vulnerabilities have been discovered in the QEMU processor
emulator. The Common Vulnerabilities and Exposures project identifies the
following problems:

CVE-2008-0928

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

CVE-2008-1945

It was discovered that an error in the format auto detection of
removable media could lead to the disclosure of files in the
host system.

CVE-2008-4539

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.

For the stable distribution (lenny), these problems have been fixed in
version 0.9.1-10lenny1.

For the unstable distribution (sid), these problems have been fixed in
