  - LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable
    Network Graphics) raster image files. From version 1.6.0 to before 1.6.51, an out-of-bounds read
    vulnerability exists in png_image_read_composite when processing palette images with
    PNG_FLAG_OPTIMIZE_ALPHA enabled. The palette compositing code in png_init_read_transformations incorrectly
    applies background compositing during premultiplication, violating the invariant component  alpha  257
    required by the simplified PNG API. This issue has been patched in version 1.6.51. (CVE-2025-64720)
