{"id":"DEBIAN-CVE-2026-75818","details":"GNU Aspell prezip-bin contains a heap-based buffer overflow vulnerability in the decompressor in prog/prezip.c. The decompressor does not properly check buffer space, so a crafted compressed file can cause out-of-bounds read and write operations on the heap. An attacker who convinces a user to process a malicious compressed file with prezip-bin can trigger memory corruption, leading to a processs crash.    This issue was fixed in commit 15b188437f9e0192d4ac4472ad66a4e2f62a782f which will be released in version 0.60.8.3.","modified":"2026-10-07T05:00:13.349385941Z","published":"2026-10-06T11:17:29.730Z","upstream":["CVE-2026-75818"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-75818"}],"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-2026-75818.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-2026-75818.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-2026-75818.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: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"}]}
