The QMP migrate command in QEMU version 4.0.0 and earlier is vulnerable to OS command injection, which allows the remote 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 de migración QMP en QEMU versión 4.0.0 y anteriores es vulnerable a una 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 en discusión si es esto es 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/2019/06/05/CVE-2019-12928 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-668: Exposure of Resource to Wrong Sphere •

hw/ppc/spapr.c in QEMU through 3.1.0 allows Information Exposure because the hypervisor shares the /proc/device-tree/system-id and /proc/device-tree/model system attributes with a guest. hw/ppc/spapr.c en QEMU, hasta la versión 3.1.0, permite la exposición de información debido a que el hipervisor comparte los atributos del sistema en /proc/device-tree/system-id and /proc/device-tree/model con un invitado. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00094.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00040.html http://www.openwall.com/lists/oss-security/2019/02/21/1 http://www.securityfocus.com/bid/107115 https://lists.gnu.org/archive/html/qemu-devel/2019-02/msg04821.html https://security.netapp.com/advisory/ntap-20190411-0006 • CWE-668: Exposure of Resource to Wrong Sphere •

QEMU, through version 2.10 and through version 3.1.0, is vulnerable to an out-of-bounds read of up to 128 bytes in the hw/i2c/i2c-ddc.c:i2c_ddc() function. A local attacker with permission to execute i2c commands could exploit this to read stack memory of the qemu process on the host. QEMU, hasta la versión 2.10 y la 3.1.0, es vulnerable a una lectura fuera de límites de hasta 128 bytes en la función hw/i2c/i2c-ddc.c:i2c_ddc(). Un atacante local con permisos para ejecutar comandos i2c podría aprovechar este hecho para leer la memoria de pila del proceso qemu en el host. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00094.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00040.html http://www.securityfocus.com/bid/107059 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3812 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CGCFIFSIWUREEQQOZDZFBYKWZHXCWBZN https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KJMTVGDLA654HNCDGLCUEIP36SNJEKK7 https://seclists.org/bugtraq&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
