{"id":"DEBIAN-CVE-2026-75820","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.    This issue was fixed in commit 782ce94e4dc71eaec4ee1bd945eb3b9c47c5387d which will be released in version 0.60.8.3.","modified":"2026-10-07T05:00:13.345994100Z","published":"2026-10-06T11:17:30.020Z","upstream":["CVE-2026-75820"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-75820"}],"affected":[{"package":{"name":"aspell","ecosystem":"Debian:12","purl":"pkg:deb/debian/aspell?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.60.8-4","0.60.8-5","0.60.8-6","0.60.8.1-1","0.60.8.1-2","0.60.8.1-3","0.60.8.1-4","0.60.8.1-5","0.60.8.1-6","0.60.8.2-1","0.60.8.2-2","0.60.8.2-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-75820.json"}},{"package":{"name":"aspell","ecosystem":"Debian:13","purl":"pkg:deb/debian/aspell?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.60.8.1-4","0.60.8.1-5","0.60.8.1-6","0.60.8.2-1","0.60.8.2-2","0.60.8.2-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-75820.json"}},{"package":{"name":"aspell","ecosystem":"Debian:14","purl":"pkg:deb/debian/aspell?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.60.8.1-4","0.60.8.1-5","0.60.8.1-6","0.60.8.2-1","0.60.8.2-2","0.60.8.2-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-75820.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
