Fix CVE-2022-2085: A NULL pointer dereference vulnerability was found in
Ghostscript, which occurs when it tries to render a large number of bits
in memory. When allocating a buffer device, it relies on an
init_device_procs defined for the device that uses it as a prototype
that depends upon the number of bits per pixel. For bpp > 64,
mem_x_device is used and does not have an init_device_procs defined.
This flaw allows an attacker to parse a large number of bits (more than
64 bits per pixel), which triggers a NULL pointer dereference flaw,
causing an application to crash.

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 OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
