Security Advisory: CVE-2025-64506
ubi-micro-dev Opinion:
This is a false positive. The vulnerable code from `libpng`
only exists in `libsplashscreen.so`, which is not part of any
`java-*-openjdk-headless` package. The vulnerable library is
distributed in `java-*-openjdk`, which is not installed in this
container image. The Red Hat product security team has been
asked to make this annotation on their CVE pages.
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, a heap buffer over-read vulnerability exists in libpng's png_write_image_8bit function when processing 8-bit images through the simplified write API with convert_to_8bit enabled. The vulnerability affects 8-bit grayscale+alpha, RGB/RGBA, and images with incomplete row data. A conditional guard incorrectly allows 8-bit input to enter code expecting 16-bit input, causing reads up to 2 bytes beyond allocated buffer boundaries. This issue has been patched in version 1.6.51.
