  "title": "Integer Truncation Leading to Heap Corruption in GNU Aspell",
  "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.    This issue was fixed in commit 782ce94e4dc71eaec4ee1bd945eb3b9c47c5387d\u00A0which will be\u00A0released in version\u00A00.60.8.3.",
