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."

Tavis Ormandy also discovered insufficient input validation leading to
a heap overflow in the NE2000 network driver in Xen. If the driver is
in use, a malicious local administrator of a guest domain could
potentially trigger this flaw and execute arbitrary code outside of
the domain (CVE-2007-1321, CVE-2007-5729, CVE-2007-5730).

Steve Kemp found that xen-utils used insecure temporary files within
the xenmon tool that could allow local users to truncate arbitrary
files (CVE-2007-3919).

Joris van Rantwijk discovered a flaw in Pygrub, which is used as a
boot loader for guest domains. A malicious local administrator of a
guest domain could create a carefully-crafted grub.conf file which
could trigger the execution of arbitrary code outside of that domain
(CVE-2007-4993).

"Multiple vulnerabilities have been found in Qemu.

Multiple heap-based buffer overflows in the cirrus_invalidate_region
function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and
possibly other products, might allow local users to execute arbitrary
code via unspecified vectors related to attempting to mark
non-existent regions as dirty, aka the bitblt heap overflow.
(CVE-2007-1320)

Integer signedness error in the NE2000 emulator in QEMU 0.8.2, as used
in Xen and possibly other products, allows local users to trigger a
heap-based buffer overflow via certain register values that bypass
sanity checks, aka QEMU NE2000 receive integer signedness error.
(CVE-2007-1321)

QEMU 0.8.2 allows local users to halt a virtual machine by executing
the icebp instruction. (CVE-2007-1322)

QEMU 0.8.2 allows local users to crash a virtual machine via the
divisor operand to the aam instruction, as demonstrated by aam 0x0,
which triggers a divide-by-zero error. (CVE-2007-1366)

The NE2000 emulator in QEMU 0.8.2 allows local users to execute
arbitrary code by writing Ethernet frames with a size larger than the
MTU to the EN0_TCNT register, which triggers a heap-based buffer
overflow in the slirp library, aka NE2000 mtu heap overflow.
(CVE-2007-5729)

Heap-based buffer overflow in QEMU 0.8.2, as used in Xen and possibly
other products, allows local users to execute arbitrary code via
crafted data in the net socket listen option, aka QEMU net socket heap
overflow. (CVE-2007-5730)

QEMU 0.9.0 allows local users of a Windows XP SP2 guest operating
system to overwrite the TranslationBlock (code_gen_buffer) buffer, and
probably have unspecified other impacts related to an overflow, via
certain Windows executable programs, as demonstrated by qemu-dos.com.
(CVE-2007-6227)

Qemu 0.9.1 and earlier does not perform range checks for block device
read or write requests, which allows guest host users with root
privileges to access arbitrary memory and escape the virtual machine.
(CVE-2008-0928)

Changing removable media in QEMU could trigger a bug similar to
CVE-2008-2004, which would allow local guest users to read arbitrary
files on the host by modifying the header of the image to identify a
different format. (CVE-2008-1945) See the diskformat: parameter to the
-usbdevice option.

The drive_init function in QEMU 0.9.1 determines the format of a raw
disk image based on the header, which allows local guest users to read
arbitrary files on the host by modifying the header to identify a
different format, which is used when the guest is restarted.
(CVE-2008-2004) See the -format option.

The updated packages have been patched to fix these issues."
