Amazon Linux 2023 Security Advisory: ALAS2023-2025-1332
Advisory Released Date: 2026-01-07
Advisory Updated Date: 2026-01-07
Severity:
Important
Issue Overview:
LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Prior to 1.6.52, an out-of-bounds read vulnerability in libpng's simplified API allows reading up to 1012 bytes beyond the png_sRGB_base[512] array when processing valid palette PNG images with partial transparency and gamma correction. The PNG files that trigger this vulnerability are valid per the PNG specification; the bug is in libpng's internal state management. Upgrade to libpng 1.6.52 or later. (CVE-2025-66293)
