In 3.6.1 and earlier, MaybeFlipBitmap() asks GDI+ to read the attacker-controlled PropertyTagOrientation size through GetPropertyItem() while supplying only a fixed 64-byte buf on the stack. Opening a crafted TIFF with enough EXIF Orientation values can cause attacker-selected bytes to overwrite stack control data, while tested builds terminate through the stack cookie check. No broader impact is claimed beyond the advisory-supported conditions. No fixed version is available as of this review.","state":0,"publishedAt":"2026-10-08T22:33:16.166+00:00","modifiedAt":"2026-10-09T15:12:35.54+00:00","affected":[{"ecosystem":"Vendor product","name":"sumatrapdf","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"sumatrapdfreader\",\n                    \"product\": \"sumatrapdf\",\n                    \"versions\": [\n                        {\n                            \"version\": \"<= 3.6.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":6.8,"severity":"MEDIUM"}],"references":["https://github.com/sumatrapdfreader/sumatrapdf/security/advisories/GHSA-px68-7vwv-mxpr","https://github.com/sumatrapdfreader/sumatrapdf/commit/6fe2e0239d8ef3466174ac92f3f56e967ce1a4a7"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107736","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107736","identifiers":["CVE-2026-107736"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
