CVE-2026-25646:
NixOS vulnerability analysis and mitigation
LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Prior to 1.6.55, an out-of-bounds read vulnerability exists in the png_set_quantize() API function. When the function is called with no histogram and the number of colors in the palette is more than twice the maximum supported by the user's display, certain palettes will cause the function to enter into an infinite loop that reads past the end of an internal heap-allocated buffer. The images that trigger this vulnerability are valid per the PNG specification. This vulnerability is fixed in 1.6.55.
Wiz Threat Research note: This vulnerability's CVSS vector has been overridden to Confidentiality and Integrity NONE by the Wiz Research team, as there is no proven impact beyond denial-of-service as of yet.
