"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."
