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."}], "lastModified": "2025-11-26T18:28:32.220", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:libpng:libpng:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "A8B5D980-7DA8-4291-8723-4CDDF73B19F6", "versionEndExcluding": "1.6.51"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
