From version 1.6.0 to before 1.6.51, a heap buffer over-read vulnerability exists in libpng's png_write_image_8bit function when processing 8-bit images through the simplified write API with convert_to_8bit enabled. The vulnerability affects 8-bit grayscale+alpha, RGB/RGBA, and images with incomplete row data. A conditional guard incorrectly allows 8-bit input to enter code expecting 16-bit input, causing reads up to 2 bytes beyond allocated buffer boundaries. This issue has been patched in version 1.6.51."}, {"lang": "es", "value": "LIBPNG es una biblioteca de referencia para su uso en aplicaciones que leen, crean y manipulan archivos de imagen r\u00e1ster PNG (Portable Network Graphics).
