13 Dec 2018 — 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 ... • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00042.html • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
