    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
    version 0.9.1+svn20081101-1.
    
    We recommend that you upgrade your qemu packages.
