- CVE-2025-68431:
libheif is an HEIF and AVIF file format decoder and encoder. Prior to
version 1.21.0, a crafted HEIF that exercises the overlay image item
path triggers a heap buffer over-read in `HeifPixelImage::overlay()`.
The function computes a negative row length (likely from an unclipped
overlay rectangle or invalid offsets), which then underflows when
converted to `size_t` and is passed to `memcpy`, causing a very large
read past the end of the source plane and a crash. Version 1.21.0
contains a patch. As a workaround, avoid decoding images using `iovl`
overlay boxes.

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 https://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.
