Package : qemu
Vulnerability : several vulnerabilities
Problem-Scope : 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 testing distribution (lenny) this is fixed in version
0.8.2-5lenny1
The package for the powerpc architecture is still missing. It will be
released when it becomes available.
For the unstable distribution (sid) this is fixed in version
0.9.0-2
This upgrade is recommended if you use qemu.
