{"id":"DEBIAN-CVE-2026-75819","details":"GNU Aspell contains an out-of-bounds read vulnerability in ReadOnlyDict::load() in readonly_ws.cpp. When loading a binary .rws dictionary file, it uses offset fields from the file header as byte indices into a heap buffer without validating their bounds. An attacker can trigger this by convincing a user to run aspell with a crafted dictionary file supplied through --master, --dict-dir, or configuration options, leading to heap memory disclosure or a denial of service via application crash.    This issue was fixed in commit 941953b25031bc9104e83f58e138a664b8dedc3f which will be released in version 0.60.8.3.","modified":"2026-10-07T05:00:13.335556393Z","published":"2026-10-06T11:17:29.883Z","upstream":["CVE-2026-75819"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-75819"}],"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-2026-75819.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-2026-75819.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-2026-75819.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:L/SI:N/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"}]}
