https://github.com/strukturag/libheif/releases/tag/v1.23.2 Fixes the following CVEs: (CVE numbers will be added upstream when assigned.) CVE-2026-XXXXX (GHSA-g89c-p67h-r497) Heap buffer overflow in scale_nearest_neighbor() via duplicate alpha planes from nested iden/auxl items. (critical) (GHSA-2jg2-4ch7-h545) Out-of-bounds read and write in derived-item and pixel-plane handling. Through iden and auxl item chains, a crafted file could attach pixel planes whose size differs from the image geometry; crop, scale, and plane-extraction code then indexed those planes with the wrong size. A working code-execution exploit was confirmed. Plane sizes are now validated wherever they are consumed. (critical) CVE-2026-XXXXX (GHSA-24wx-9w62-c96w) brotli/zlib decompression of mime metadata and unci image data had no effective output-size limit, so a decompression bomb could exhaust memory. Decompressed output is now bounded by the security limits. (high) CVE-2026-XXXXX (GHSA-x8xm-cm2c-cfc8) Chains of derived-image references (grid, iovl, iden) bypassed decode caching and memory limits, causing CPU and memory amplification. (high) CVE-2026-XXXXX (GHSA-xw34-mjcp-jqh8) Sequence sample-timing initialization could produce non-terminating decode loops and unbounded memory, bypassing max_sequence_frames. (high) CVE-2026-XXXXX (GHSA-j264-xvrp-5v7q) Out-of-bounds write in the unci encoder when heif_context_add_image_tile() is given a tile whose planes do not match its declared size. (high) CVE-2026-XXXXX (GHSA-p58j-h3vm-3fp5) Heap out-of-bounds read in the inline-mask region API when mask_data_len does not match the region geometry.

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