It was discovered that the e1000 emulation code in QEMU does not enforce frame size limits in the same way as the real hardware does. This could trigger buffer overflows in the guest operating system driver for that network card, assuming that the host system does not discard such frames (which it will by default).

For the stable distribution (squeeze), this problem has been fixed in version 0.12.5+dfsg-3squeeze3. For the unstable distribution (sid), this problem has been fixed in version 1.1.2+dfsg-4. We recommend that you upgrade your qemu packages.

QEMU is a fast processor emulator: currently the package supports ARM, CRIS, i386, M68k (ColdFire), MicroBlaze, MIPS, PowerPC, SH4, SPARC and x86-64 emulation. By using dynamic translation it achieves reasonable speed while being easy to port on new host CPUs. QEMU has two operating modes:
