A heap buffer overflow existed when importing an EMF+ gradient brush. The number of gradient blend points was read from the file and used to compute an allocation size, but that multiplication could overflow, so a small buffer was allocated and then filled as if it were large, writing past its end. In fixed versions the blend-point count is checked against the data actually available before allocating.","state":0,"publishedAt":"2026-06-15T16:22:16.574+00:00","modifiedAt":"2026-10-21T09:30:52.886+00:00","affected":[{"ecosystem":"Vendor product","name":"LibreOffice","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"The Document Foundation\",\n                    \"product\": \"LibreOffice\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"25.8\",\n                            \"lessThan\": \"< 25.8.7\",\n                            \"versionType\": \"25.8 series\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"26.2\",\n                            \"lessThan\": \"< 26.2.3\",\n                            \"versionType\": \"26.2 series\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unknown\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N/E:P","score":5.4,"severity":"MEDIUM"}],"references":["https://www.libreoffice.org/about-us/security/advisories/cve-2026-6045"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-6045","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-6045","identifiers":["CVE-2026-6045"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
