Description Lubomir Kundrak 2007-10-31 15:11:01 UTC 
Common Vulnerabilities and Exposures assigned an identifier CVE-2007-5729 to the following vulnerability:

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.  NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of 
"
NE2000 network driver and the socket code,
"
 but this is the correct identifier for the mtu overflow vulnerability.
