QEMU has two operating modes: * Full system emulation. In this mode, QEMU emulates a full system (for example a PC), including a processor and various peripherials. It can be used to launch different Operating Systems without rebooting the PC or to debug system code. * User mode emulation. In this mode, QEMU can launch Linux processes compiled for one CPU on another CPU.

Debian: DSA-2610-1 Urgent: QEMU Network Adapter Vulnerability Found

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.
