Package        : qemu
Vulnerability  : several
Problem-Type   : local
Debian-specific: no
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:


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


    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.


    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.
