LodePNG through 20261006 contains a heap out-of-bounds read vulnerability in lodepng::getFilterTypesInterlaced() in lodepng_util.cpp that lacks bounds checks on decompressed IDAT data. Attackers can supply a crafted interlaced PNG declaring a raster larger than its IDAT stream to disclose adjacent heap memory or crash applications.
