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.","state":0,"publishedAt":"2026-10-19T13:55:21.345+00:00","modifiedAt":"2026-10-19T17:57:12.363+00:00","affected":[{"ecosystem":"https://github.com/mfontanini/libtins","name":"libtins","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"libtins\",\n                    \"product\": \"libtins\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"4.6\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"collectionURL\": \"https://github.com/mfontanini/libtins\",\n                    \"repo\": \"https://github.com/mfontanini/libtins\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":6.3,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","score":3.7,"severity":"LOW"}],"references":["https://hackmd.io/@haindpwn/libtins-dns-name-parsing-oob-read","https://github.com/mfontanini/libtins/blob/v4.6/src/dns.cpp#L698-L710","https://github.com/mfontanini/libtins","https://www.vulncheck.com/advisories/libtins-through-4.6-out-of-bounds-read-via-dns-soa-record-init"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112274","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112274","identifiers":["CVE-2026-112274"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
