{"schema":"threatline.record/2","record":{"id":"CVE-2026-75820","aliases":[],"summary":"Integer Truncation Leading to Heap Corruption in GNU Aspell","details":"GNU Aspell contains an integer truncation vulnerability in the WritableDict::add() function in modules/speller/default/writable.cpp. When loading a personal wordlist, the word length is stored as a single byte, causing truncation for words whose length is a multiple of 256. 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 which will be released in version 0.60.8.3.","categories":["Unclassified"],"product":"Aspell","vendor":"GNU","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-75820","source_modified_at":"2026-10-06T12:49:39.265Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Aspell","vendor":"GNU","versions":[{"status":"affected","version":"0","lessThan":"0.60.8.3","versionType":"semver"}],"defaultStatus":"unknown"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-75820","source_modified_at":"2026-10-06T12:49:39.265Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Aspell","ecosystem":null},"version":"0.60.8.3","basis":"first unaffected version stated in the CVE record"}],"cvss":1.8,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00125,"percentile":0.02061,"score_date":"2026-10-23"},"published_at":"2026-10-06T10:57:59.621Z","modified_at":"2026-10-06T12:49:39.265Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-75820","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-06T12:49:39.265Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-75820","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://cert.pl/en/posts/2026/10/CVE-2026-75818","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-06T12:49:13.392681Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-06T12:49:39.265Z","content_hash":"60f0982ce9f80f6af6a0c3c946c2a16dbf49e636cd207066267e476ba5a9b1d1"}}
