Attackers can feed raw SOA RDATA without a zero byte to applications using the buffer constructor, causing strlen to overrun the heap buffer and possibly crash.","categories":["Unclassified"],"product":"libtins","vendor":"libtins","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-112274","source_modified_at":"2026-10-19T17:57:12.363Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"libtins","vendor":"libtins","versions":[{"version":"0","lessThanOrEqual":"4.6","status":"affected","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00521,"percentile":0.43435,"score_date":"2026-10-23"},"published_at":"2026-10-19T13:55:21.345Z","modified_at":"2026-10-19T17:57:12.363Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-112274","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T17:57:12.363Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-112274","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://hackmd.io/@haindpwn/libtins-dns-name-parsing-oob-read","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/mfontanini/libtins/blob/v4.6/src/dns.cpp#L698-L710","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/mfontanini/libtins","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/libtins-through-4.6-out-of-bounds-read-via-dns-soa-record-init","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-19T17:56:57.348204Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-19T17:57:12.363Z","content_hash":"cf682940d3ee0244a7df4ac28099c01fab3406629d62b2e502aeb82cd2fcb7c4"}}
