LIBPNG heap buffer overflow
CVE: CVE-2025-65018
Component: libpng
CWE: CWE-787
Severity: Important
CVSS v3: 7.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H
Release date: 2025-11-24T23:50:18.294000+00:00

A buffer overflow flaw has been discovered in libpng. 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.

Statement: This vulnerability is rated Important for Red Hat products. A heap buffer overflow exists in the libpng library's png_image_finish_read function when processing specially crafted 16-bit interlaced PNG images with an 8-bit output format. Successful exploitation requires a user or an automated system to process a malicious PNG file, which could lead to application crashes or arbitrary code execution.

java-*-openjdk-headless packages do not contain libsplashscreen.so, hence are not affected.
