What is CVE-2007-5729?
CVE-2007-5729 is a high-severity memory corruption vulnerability in Debian Debian Linux, published on 30 Oct 2007. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
