Hi, The following vulnerability was published for qemu. CVE-2018-16872[0]: | A flaw was found in qemu Media Transfer Protocol (MTP). The code | opening files in usb_mtp_get_object and usb_mtp_get_partial_object and | directories in usb_mtp_object_readdir doesn't consider that the | underlying filesystem may have changed since the time lstat(2) was | called in usb_mtp_object_alloc, a classical TOCTTOU problem. An | attacker with write access to the host filesystem shared with a guest | can use this property to navigate the host filesystem in the context | of the QEMU process and read any file the QEMU process has access to. | Access to the filesystem may be local or via a network share protocol | such as CIFS. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
