CVE-2025-65018 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. 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. EPSS estimates a 0.22% chance of exploitation in the next 30 days.

Description

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.
