CVE-2007-5729: QEMU 0.8.2 NE2000 emulation can let local users run code
CVE-2007-5729 · published 19 years ago
Summary
The QEMU virtualization program version 0.8.2 includes a network‑adapter emulator (NE2000) that can be tricked into overflowing its memory when a local user sends an overly large Ethernet frame. This memory overflow can allow the attacker to run any program they choose on the host machine. Update QEMU to a newer version or apply the vendor’s patch to stop the problem.
What to do
- Update debian qemu to version 0.9.0-2.

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.
