https://notcve.org/view.php?id=CVE-2020-13754
hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address in an msi-x mmio operation. En el archivo hw/pci/msix.c en QEMU versión 4.2.0, permite a usuarios invitados del SO desencadenar un acceso fuera de límites por medio de una dirección diseñada en una operación msi-x mmio. An out-of-bounds access flaw was found in the Message Signalled Interrupt (MSI-X) device support of QEMU. This issue occurs while performing MSI-X mmio operations when a guest sent address goes beyond the mmio region. A guest user or process may use this flaw to crash the QEMU process resulting in a denial of service. • http://www.openwall.com/lists/oss-security/2020/06/01/6 http://www.openwall.com/lists/oss-security/2020/06/15/8 https://lists.debian.org/debian-lts-announce/2020/07/msg00020.html https://lists.gnu.org/archive/html/qemu-devel/2020-06/msg00004.html https://security.gentoo.org/glsa/202011-09 https://security.netapp.com/advisory/ntap-20200608-0007 https://usn.ubuntu.com/4467-1 https://www.debian.org/security/2020/dsa-4728 https://access.redhat.com/security/cve&#x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

In QEMU 5.0.0 and earlier, megasas_lookup_frame in hw/scsi/megasas.c has an out-of-bounds read via a crafted reply_queue_head field from a guest OS user. En QEMU versión 5.0.0 y versiones anteriores, la función megasas_lookup_frame en el archivo hw/scsi/megasas.c presenta una lectura fuera de límites mediante el campo reply_queue_head desde un usuario invitado del Sistema Operativo. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00086.html http://www.openwall.com/lists/oss-security/2020/05/28/2 https://lists.debian.org/debian-lts-announce/2020/06/msg00032.html https://lists.debian.org/debian-lts-announce/2020/07/msg00020.html https://lists.gnu.org/archive/html/qemu-devel/2020-05/msg03131.html https://lists.gnu.org/archive/html/qemu-devel/2020-05/msg06250.html https://security-tracker.debian.org/tracker/CVE-2020-13362 https://security • CWE-125: Out-of-bounds Read •

In QEMU 5.0.0 and earlier, es1370_transfer_audio in hw/audio/es1370.c does not properly validate the frame count, which allows guest OS users to trigger an out-of-bounds access during an es1370_write() operation. En QEMU versión 5.0.0 y versiones anteriores, la función es1370_transfer_audio en el archivo hw/audio/es1370.c no comprueba apropiadamente el conteo de tramas, lo que permite a usuarios invitados del Sistema Operativo desencadenar un acceso fuera de límites durante una operación es1370_write(). • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00086.html http://www.openwall.com/lists/oss-security/2020/05/28/1 https://lists.debian.org/debian-lts-announce/2020/06/msg00032.html https://lists.debian.org/debian-lts-announce/2020/07/msg00020.html https://lists.gnu.org/archive/html/qemu-devel/2020-05/msg03983.html https://security-tracker.debian.org/tracker/CVE-2020-13361 https://security.gentoo.org/glsa/202011-09 https://security.netapp.com/advisory/ntap-202 • CWE-787: Out-of-bounds Write •

The QMP guest_exec command in QEMU 4.0.0 and earlier is prone to OS command injection, which allows the attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue **EN DISPUTA** El comando QMP guest_exec en QEMU versión 4.0.0 y anteriores es propenso a la inyección de comandos del sistema operativo, lo que permite al atacante remoto lograr la ejecución de código, una denegación de servicio, o la divulgación de información mediante el envío de un comando QMP manipulado al servidor de escucha. Nota: Está siendo discutida por no ser un problema ya que la interfaz -qmp de QEMU está destinada a ser utilizada por usuarios de confianza. Si uno puede acceder a esta interfaz a través de un socket TCP abierto a Internet, entonces es un problema de configuración inseguro. • https://fakhrizulkifli.github.io/posts/2019/06/06/CVE-2019-12929 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-668: Exposure of Resource to Wrong Sphere •
