{"id":"CVE-2026-110604","summary":"Mini-XML 4.0.0 through 4.0.6 Stack Out-of-Bounds Write via mxml_strtod()","details":"Mini-XML 4.0.0 through 4.0.6 contains an off-by-one stack out-of-bounds write in mxml_strtod() when the locale decimal point is not '.'. Attackers can supply XML with a 63-digit REAL value followed by '.' to write a NUL byte past the 64-byte stack buffer, corrupting stack memory or crashing the process.","modified":"2026-10-15T02:47:30.996906670Z","published":"2026-10-14T14:16:44.995Z","database_specific":{"cwe_ids":["CWE-193"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110604.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110604.json"},{"type":"PACKAGE","url":"https://github.com/michaelrsweet/mxml"},{"type":"ARTICLE","url":"https://github.com/michaelrsweet/mxml/blob/v4.0.6/mxml-file.c#L1860-L1887"},{"type":"FIX","url":"https://github.com/michaelrsweet/mxml/commit/367c7ddd3387f65e867d776216de274bcaa3dae1"},{"type":"EVIDENCE","url":"https://hackmd.io/@haind-pwn/cve-2026-110604-mxml-strtod-locale-stack-overflow"},{"type":"ADVISORY","url":"https://hackmd.io/@haind-pwn/mxml-strtod-locale-stack-overflow"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110604"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/mini-xml-4.0.0-through-4.0.6-stack-out-of-bounds-write-via-mxml-strtod"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/michaelrsweet/mxml","events":[{"introduced":"9856aa51e3449ffd2b589fb2480f1b18bc006ea2"},{"last_affected":"874e249a0d3b506e883210b7ceece5316a8489d4"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"4.0.0"},{"last_affected":"4.0.6"}]}}],"versions":["v4.0.6","v4.0.5","v4.0.4","v4.0.3","v4.0.2","v4.0.1","v4.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110604.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:P/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N"}]}
