QEMU heap buffer overflow vulnerability (CNVD-2020-54916)

QEMU is a set of simulation processors written by Fabrice Bellard and distributed with source code under the GPL license, widely used on the GNU/Linux platform. A security vulnerability exists in QEMU, which originates in hw/sd/sdhci.c that triggers a memory corruption, which triggers a denial of...

Heap-based buffer overflow in the .receive callback of xlnx.xps-ethernetlite in QEMU (aka Quick Emulator) allows attackers to execute arbitrary code on the QEMU host via a large ethlite packet.

An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in do_token_out routines. This flaw allows a guest user 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.
