This flaw is strictly related to CVE-2018-13405. A local guest user can create files in the directories shared by virtio-fs with unintended group ownership in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of the group. This could allow a malicious unprivileged user inside the guest to gain access to resources accessible to the root group, potentially escalating their privileges within the guest. A malicious local user in the host might also leverage this unexpected executable file created by the guest to escalate their privileges on the host system."}, {"lang": "es", "value": "Se ha encontrado un fallo en la implementaci\u00f3n del demonio del sistema de archivos compartidos de QEMU virtio-fs (virtiofsd).
