https://notcve.org/view.php?id=CVE-2017-5973
The xhci_kick_epctx function in hw/usb/hcd-xhci.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (infinite loop and QEMU process crash) via vectors related to control transfer descriptor sequence. La función xhci_kick_epctx en hw/usb/hcd-xhci.c en QEMU (también conocido como Quick Emulator) permite a usuarios locales privilegiados del SO invitado provocar una denegación de servicio (bucle infinito y caída del proceso QEMU) a través de vectores relacionados con la secuencia del descriptor de transferencia de control. • http://git.qemu-project.org/?p=qemu.git%3Ba=commit%3Bh=f89b60f6e5fee3923bedf80e82b4e5efc1bb156b http://www.openwall.com/lists/oss-security/2017/02/13/11 http://www.securityfocus.com/bid/96220 https://access.redhat.com/errata/RHSA-2017:2392 https://access.redhat.com/errata/RHSA-2017:2408 https://bugzilla.redhat.com/show_bug.cgi?id=1421626 https://lists.debian.org/debian-lts-announce/2018/09/msg00007.html https://lists.gnu.org/archive/html/qemu-devel/2017-02/msg01101.html https: • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVSS: 9.3EPSS: 1%CPEs: 3EXPL: 1CVE-2016-9587 – Ansible 2.1.4/2.2.1 - Command Execution
https://notcve.org/view.php?id=CVE-2016-9587
Ansible before versions 2.1.4, 2.2.1 is vulnerable to an improper input validation in Ansible's handling of data sent from client systems. An attacker with control over a client system being managed by Ansible and the ability to send facts back to the Ansible server could use this flaw to execute arbitrary code on the Ansible server using the Ansible server privileges. Ansible, en versiones anteriores a la 2.1.4 y la 2.2.1, es vulnerable a una validación de entradas incorrecta en la gestión de Ansible de datos enviados desde los sistemas de clientes. Un atacante que tenga el control de un sistema de cliente gestionado por Ansible y la capacidad de enviar hechos de vuelta al servidor de Ansible podría usar este error para ejecutar código arbitrario en el servidor de Ansible utilizando los privilegios del servidor de Ansible. An input validation vulnerability was found in Ansible's handling of data sent from client systems. • https://www.exploit-db.com/exploits/41013 http://rhn.redhat.com/errata/RHSA-2017-0195.html http://rhn.redhat.com/errata/RHSA-2017-0260.html http://www.securityfocus.com/bid/95352 https://access.redhat.com/errata/RHSA-2017:0448 https://access.redhat.com/errata/RHSA-2017:0515 https://access.redhat.com/errata/RHSA-2017:1685 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-9587 https://security.gentoo.org/glsa/201701-77 https://access.redhat.com/security/cve/C • CWE-20: Improper Input Validation •
