Descriptions
The patch for CVE-2020-17380/CVE-2020-25085 was found to be ineffective, thus making QEMU vulnerable to the out-of-bounds read/write access issues previously found in the SDHCI controller emulation code. This flaw allows a malicious privileged guest to crash the QEMU process on the host, resulting in a denial of service or potential code execution. QEMU up to (including) 5.2.0 is affected by this.
Se detectó que el parche para CVE-2020-17380/CVE-2020-25085 era ineficaz, por lo que QEMU era vulnerable a problemas de acceso de lectura y escritura fuera de límites que se encontraban anteriormente en el código de emulación del controlador SDHCI. Este fallo permite a un invitado privilegiado malicioso bloquear el proceso QEMU en el host, resultando en una denegación de servicio o una posible ejecución de código. QEMU versiones hasta (incluyendo) 5.2.0 está afectado por esto
