Add an upstream patch to fix CVE-2020-35492:
A flaw was found in cairo's image-compositor.c in all versions prior to
1.17.4. This flaw allows an attacker who can provide a crafted input
file to cairo's image-compositor (for example, by convincing a user to
open a file in an application using cairo, or if an application uses
cairo on untrusted input) to cause a stack buffer overflow ->
out-of-bounds WRITE. The highest impact from this vulnerability is to
confidentiality, integrity, as well as system availability.
Important note: this is not the exact upstream patch. Indeed, the
upstream patch[1] contains a png file which appears as a binary diff
inside the patch. The `patch` tool which is used by Buildroot to apply
patches does not handle that kind of diff. Since it is just a test, it
shouldn't impact the quality of the CVE fix and all changes related to
the test are removed from the patch.

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
