20 Feb 2024 — QEMU before 8.2.0 has an integer underflow, and resultant buffer overflow, via a TI command when an expected non-DMA transfer length is less than the length of the available FIFO data. This occurs in esp_do_nodma in hw/scsi/esp.c because of an underflow of async_len. QEMU anterior a 8.2.0 tiene un desbordamiento de número entero y un desbordamiento de búfer resultante, a través de un comando TI cuando una longitud de transferencia esperada que no es DMA es menor que la longitud de los datos FIFO disponibles... • https://gist.github.com/1047524396/5ce07b9d387095c276b1cd234ae5615e • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-191: Integer Underflow (Wrap or Wraparound) •

12 Jan 2024 — A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the chance to initialize the clipboard peer, leading to a NULL pointer dereference.

02 Jan 2024 — A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the `out_sg` variable could be used to read a part of process memory and send it to the wire, causing an information leak.

03 Nov 2023 — A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot.
