Descriptions

A heap-based buffer overflow was found in QEMU through 5.0.0 in the SDHCI device emulation support. It could occur while doing a multi block SDMA transfer via the sdhci_sdma_transfer_multi_blocks() routine in hw/sd/sdhci.c. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code with privileges of the QEMU process on the host.

Se encontró un desbordamiento del búfer en la región heap de la memoria en QEMU versiones hasta 5.0.0, en el soporte de emulación de dispositivo SDHCI. Podría ocurrir mientras se realiza una transferencia SDMA de bloques múltiples por medio de la rutina sdhci_sdma_transfer_multi_blocks() en el archivo hw/sd/sdhci.c. Un usuario o proceso invitado podría usar este fallo para bloquear el proceso QEMU en el host, resultando en una condición de denegación de servicio, o potencialmente ejecutar código arbitrario con privilegios del proceso QEMU en el host
