CVE-2026-75820
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. This issue was fixed in commit 782ce94e4dc71eaec4ee1bd945eb3b9c47c5387d which will be released in version 0.60.8.3.
