{"id":"CVE-2026-75820","published":"2026-10-06T11:17:30.020","lastModified":"2026-10-06T15:03:59.427","description":"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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-190"],"vendors":[],"products":[],"references":[{"url":"http://aspell.net/","tags":[]},{"url":"https://cert.pl/en/posts/2026/10/CVE-2026-75818","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
