This leads to heap corruption. An attacker can exploit this by convincing a user to run aspell with a crafted personal wordlist containing such a word, resulting in denial of service.\n\n\n\nThis issue was fixed in commit 782ce94e4dc71eaec4ee1bd945eb3b9c47c5387d\u00A0which will be\u00A0released in version\u00A00.60.8.3.","state":0,"publishedAt":"2026-10-06T10:57:59.621+00:00","modifiedAt":"2026-10-06T12:49:39.265+00:00","affected":[{"ecosystem":"Vendor product","name":"Aspell","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"GNU\",\n                    \"product\": \"Aspell\",\n                    \"repo\": \"https://github.com/GNUAspell/aspell\",\n                    \"modules\": [\n                        \"WritableDict::add()\"\n                    ],\n                    \"programFiles\": [\n                        \"modules/speller/default/writable.cpp\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"0.60.8.3\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unknown\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:L/SA:N","score":1.8,"severity":"LOW"}],"references":["https://cert.pl/en/posts/2026/10/CVE-2026-75818","http://aspell.net/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-75820","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-75820","identifiers":["CVE-2026-75820"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
