    Several vulnerabilities have been discovered in the QEMU processor
    emulator, which may lead to the execution of arbitrary code or denial of
    service. The Common Vulnerabilities and Exposures project identifies the
    following problems:
    
    CVE-2007-1320
        Tavis Ormandy discovered that a memory management routine of the Cirrus
        video driver performs insufficient bounds checking, which might
        allow the execution of arbitrary code through a heap overflow.
    
    CVE-2007-1321
        Tavis Ormandy discovered that the NE2000 network driver and the socket
        code perform insufficient input validation, which might allow the
        execution of arbitrary code through a heap overflow.
    
    CVE-2007-1322
        Tavis Ormandy discovered that the "icebp" instruction can be abused to
        terminate the emulation, resulting in denial of service.
    
    CVE-2007-1323
        Tavis Ormandy discovered that the NE2000 network driver and the socket
        code perform insufficient input validation, which might allow the
        execution of arbitrary code through a heap overflow.
    
    CVE-2007-1366
        Tavis Ormandy discovered that the "aam" instruction can be abused to
        crash qemu through a division by zero, resulting in denial of
        service.
    
    For the oldstable distribution (sarge) these problems have been fixed in
    version 0.6.1+20050407-1sarge1.
    
    For the stable distribution (etch) these problems have been fixed
    in version 0.8.2-4etch1.
    
    For the unstable distribution (sid) these problems will be fixed soon.
    
    We recommend that you upgrade your qemu packages.
