LIBPNG is vulnerable to a heap buffer overflow in `png_combine_row` triggered via `png_image_finish_read`

Open Source Vulnerabilities ASB-A-463998243

In multiple locations, there is a possible way to achieve remote code execution due to a heap buffer overflow. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Open Source Vulnerabilities CVE-2025-65018

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, there is a heap buffer overflow vulnerability in the libpng simplified API function png_image_finish_read when processing 16-bit interlaced PNGs with 8-bit output format. Attacker-crafted interlaced PNG files cause heap writes beyond allocated buffer bounds. This issue has been patched in version 1.6.51.
