The Xen Project reports :

The QEMU model of the RTL8139 network card did not sufficiently validate inputs in the C+ mode offload emulation. This results in uninitialized memory from the QEMU process’s heap being leaked to the domain as well as to the network.

A guest may be able to read sensitive host-level data relating to itself which resides in the QEMU process.

Such information may include things such as information relating to real devices backing emulated devices or passwords which the host administrator does not intend to share with the guest admin.
