Subject: CVE-2020-11102 QEMU: tulip: OOB access in tulip_copy_tx_buffers


An out-of-bounds access issue was found in the Tulip NIC emulator built into 
QEMU. It could occur while copying network data to/from its tx/rx frame 
buffers, as it does not check frame size against the data length.

A remote user/process could use this flaw to crash the QEMU process resulting 
in Dos OR potentially execute arbitrary code with the privileges of the QEMU 
process on the host.

Upstream patch:

This issue was reported by Ziming Zhang and Li Qiang (Ant Financial).
