Prior to version 1.6.51, a heap buffer over-read vulnerability exists in libpng's `png_do_quantize` function when processing PNG files with malformed palette indices. The vulnerability occurs when `palette_lookup` array bounds are not validated against externally-supplied image data, allowing an attacker to craft a PNG file with out-of-range palette indices that trigger out-of-bounds memory access. This issue has been patched in version 1.6.51.","modified":"2026-07-25T18:24:10.959581893Z","published":"2025-12-01T22:31:38.231Z","upstream":["CVE-2025-64505"],"database_specific":{"license":"CC-BY-4.0","sources":[{"url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2025-64505","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2025-64505","database_specific":{"status":"Analyzed"},"id":"CVE-2025-64505","imported":"2026-07-17T21:00:38.440Z","modified":"2026-06-17T09:54:28.830Z","published":"2025-11-25T00:15:47.133Z"}]},"references":[{"type":"WEB","url":"https://github.com/pnggroup/libpng/commit/6a528eb5fd0dd7f6de1c39d30de0e41473431c37"},{"type":"WEB","url":"https://github.com/pnggroup/libpng/pull/748"},{"type":"WEB","url":"https://github.com/pnggroup/libpng/security/advisories/GHSA-4952-h5wq-4m42"}],"affected":[{"package":{"name":"libpng_jll","ecosystem":"Julia","purl":"pkg:julia/libpng_jll?uuid=b53b4c65-9356-5827-b1ea-8c7a1a84506f"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.6.51+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2025/JLSEC-2025-328.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H"}]}
