| Doc Text: |
A flaw was found in libpng, a reference library for PNG (Portable Network Graphics) raster image files. An integer truncation vulnerability exists in the png_write_image_16bit and png_write_image_8bit simplified write API functions. A local attacker could exploit this flaw by providing a negative row stride (for bottom-up image layouts) or a stride exceeding 65535 bytes, leading to a heap buffer over-read. This can result in information disclosure or a denial of service (DoS) to the system.
