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-5+squeeze10. For the unstable distribution (sid), this problem has been fixed in version 1.1.2+dfsg-4. We recommend that you upgrade your qemu-kvm packages.

Using KVM, one can run multiple virtual PCs, each running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc.

This check tests the installed software version using the apt package manager.
