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.","modified":"2026-03-24T16:30:09.760396Z","published":"2026-03-24T16:21:52.681Z","upstream":["CVE-2025-66293"],"database_specific":{"license":"CC-BY-4.0","sources":[{"published":"2025-12-03T21:15:53.060Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2025-66293","id":"CVE-2025-66293","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2025-66293","imported":"2026-03-24T05:02:26.965Z","modified":"2025-12-16T19:12:50.350Z"}]},"references":[{"type":"WEB","url":"https://github.com/pnggroup/libpng/commit/788a624d7387a758ffd5c7ab010f1870dea753a1"},{"type":"WEB","url":"https://github.com/pnggroup/libpng/commit/a05a48b756de63e3234ea6b3b938b8f5f862484a"},{"type":"WEB","url":"https://github.com/pnggroup/libpng/issues/764"},{"type":"WEB","url":"https://github.com/pnggroup/libpng/security/advisories/GHSA-9mpm-9pxh-mg4f"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2025/12/03/6"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2025/12/03/7"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2025/12/03/8"},{"type":"WEB","url":"https://github.com/pnggroup/libpng/issues/764"}],"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":"1.6.53+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-6.json"}}],"schema_version":"1.7.5"}
