Oracle Linux: CVE-2020-11102: ELSA-2021-9034: qemu security update (IMPORTANT) (Multiple Advisories)
Description
hw/net/tulip.c in QEMU 4.2.0 has a buffer overflow during the copying of tx/rx buffers because the frame size is not validated against the r/w data length. An out-of-bounds access flaw was found in the Tulip NIC emulator built into QEMU. This flaw occurs while copying network data to and from its tx/rx frame buffers, as it does not check frame size against the data length. This flaw allows a remote user or process to crash the QEMU process, resulting in a denial of service or the potential execution of arbitrary code with the privileges of the QEMU process on the host.
