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.
