{"schema":"threatline.record/2","record":{"id":"CVE-2026-75818","aliases":[],"summary":"Heap Buffer Overflow in GNU Aspell's prezip utility","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.\n\n\n\nThis issue was fixed in commit 15b188437f9e0192d4ac4472ad66a4e2f62a782f which will be released in version 0.60.8.3.","categories":["Unclassified"],"product":"Aspell","vendor":"GNU","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-75818","source_modified_at":"2026-10-06T12:50:58.338Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Aspell","vendor":"GNU","versions":[{"status":"affected","version":"0","lessThan":"0.60.8.3","versionType":"semver"}],"defaultStatus":"unknown"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-75818","source_modified_at":"2026-10-06T12:50:58.338Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Aspell","ecosystem":null},"version":"0.60.8.3","basis":"first unaffected version stated in the CVE record"}],"cvss":1.8,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00138,"percentile":0.02902,"score_date":"2026-10-23"},"published_at":"2026-10-06T10:57:52.690Z","modified_at":"2026-10-06T12:50:58.338Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-75818","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-06T12:50:58.338Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-75818","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://cert.pl/en/posts/2026/10/CVE-2026-75818","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-06T12:50:34.738213Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-06T12:50:58.338Z","content_hash":"f2d24da26b82e1dcb863f0ca2963ee7ad0f77fab6f2ffe02a194bf4988e589d8"}}
