The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors.
An information leak flaw was found in the way QEMU's RTL8139 emulation implementation processed network packets under RTL8139 controller's C+ mode of operation. An unprivileged guest user could use this flaw to read up to 65 KB of uninitialized QEMU heap memory.

This issue affects the versions of kvm and xen packages as shipped with Red Hat Enterprise Linux 5. This issue affects the versions of the qemu-kvm packages as shipped with Red Hat Enterprise Linux 6 and 7. This issue affects the Red Hat Enterprise Linux 6 based versions of qemu-kvm-rhev packages as shipped with Red Hat Enterprise Virtualization 3. This issue affects the Red Hat Enterprise Linux 7 based versions of the qemu-kvm-rhev packages as shipped with Red Hat Enterprise Virtualization 3. Red Hat Enterprise Linux 5 is now in Production 3 Phase of the support and maintenance life cycle. This has been rated as having Moderate security impact and is not currently planned to be addressed in future updates.
