Package        : qemu
Vulnerability  : several
Problem-Type   : local
Debian-specific: no
CVE ID         : CVE-2007-1320 CVE-2007-1321 CVE-2007-1322 CVE-2007-1323 
CVE-2007-1366

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.


Upgrade Instructions
