https://notcve.org/view.php?id=CVE-2017-9374
Memory leak in QEMU (aka Quick Emulator), when built with USB EHCI Emulation support, allows local guest OS privileged users to cause a denial of service (memory consumption) by repeatedly hot-unplugging the device. Una pérdida de memoria en QEMU (conocido como Quick Emulator), cuando se ensambla con el soporte de emulación EHCI USB, permite a los usuarios privilegiados del sistema operativo invitado local causar una denegación de servicio (consumo de memoria) mediante una desconexión del dispositivo repetidamente. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=d710e1e7bd3d5bfc26b631f02ae87901ebe646b0 http://www.debian.org/security/2017/dsa-3920 http://www.openwall.com/lists/oss-security/2017/06/06/3 http://www.securityfocus.com/bid/98905 https://access.redhat.com/errata/RHSA-2017:2392 https://access.redhat.com/errata/RHSA-2017:2408 https://bugzilla.redhat.com/show_bug.cgi?id=1459132 https://lists.debian.org/debian-lts-announce/2018/09/msg00007.html https://access.redhat.com/security&#x • CWE-401: Missing Release of Memory after Effective Lifetime CWE-772: Missing Release of Resource after Effective Lifetime •

Quick Emulator (Qemu) built with the VirtFS, host directory sharing via Plan 9 File System (9pfs) support, is vulnerable to an improper access control issue. It could occur while accessing files on a shared host directory. A privileged user inside guest could use this flaw to access host file system beyond the shared folder and potentially escalating their privileges on a host. Quick Emulator (Qemu) interado con VirtFS, compartición de directorios host mediante el soporte 9pfs (Plan 9 File System), es vulnerable a un control de acceso incorrecto.
