When image components declare different subsampling values, the non-samescale sub-byte-depth output path allocates a row buffer sized for packed output but writes a full byte per output column regardless of bit depth, overflowing the allocation and corrupting internal chunk-allocator metadata to achieve code execution.","state":0,"publishedAt":"2026-09-15T14:26:06.697+00:00","modifiedAt":"2026-10-01T15:19:56.598+00:00","affected":[{"ecosystem":"Vendor product","name":"Ghostscript","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"affected\",\n                    \"vendor\": \"Artifex Software\",\n                    \"product\": \"Ghostscript\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"10.08.0\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://github.com/ArtifexSoftware/ghostpdl-downloads/releases/tag/gs10080","https://github.com/ArtifexSoftware/ghostpdl/commit/0a8bf88e39db07b0751a58d6ec1cf992073e4dc1","https://bugs.ghostscript.com/show_bug.cgi?id=709666","https://www.vulncheck.com/advisories/ghostscript-heap-buffer-overflow-via-jpeg-2000-output-adapter"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-39919","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-39919","identifiers":["CVE-2026-39919"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
