{"id":"CVE-2026-75820","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-75820","generatedAt":"2026-10-28T02:57:50.715Z","title":"GNU Aspell contains an integer truncation vulnerability in the WritableDict::add() function in modules/speller/default/writable.cpp.","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.","published":"2026-10-06T11:17:30.000Z","lastModified":"2026-10-06T15:03:59.000Z","status":"Deferred","sourceIdentifier":"cvd@cert.pl","cvss":{"version":"4.0","score":1.8,"severity":"LOW","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-190"],"affected":[],"epss":{"score":0.00132,"percentile":0.0277,"date":"2026-10-26","history":[{"date":"2026-10-07","score":0.00125,"percentile":0.01966}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.13%).
