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
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.
This issue does not affect Red Hat Enterprise Linux.
