Fixes the following security issues:
CVE-2018-16872: 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.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
