{"id":"UBUNTU-CVE-2026-110604","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":"2026-10-17T12:58:03.787536541Z","published":"2026-10-15T00:00:00Z","upstream":["CVE-2026-110604"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-110604"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-110604"},{"type":"REPORT","url":"https://github.com/michaelrsweet/mxml/blob/v4.0.6/mxml-file.c#L1860-L1887"},{"type":"REPORT","url":"https://github.com/michaelrsweet/mxml/commit/367c7ddd3387f65e867d776216de274bcaa3dae1"},{"type":"REPORT","url":"https://hackmd.io/@haind-pwn/mxml-strtod-locale-stack-overflow"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/mini-xml-4.0.0-through-4.0.6-stack-out-of-bounds-write-via-mxml-strtod"},{"type":"REPORT","url":"https://hackmd.io/@haind-pwn/cve-2026-110604-mxml-strtod-locale-stack-overflow"}],"affected":[{"package":{"name":"mxml","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/mxml?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7-1","2.9-0ubuntu1","2.9-0ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_name":"libmxml1","binary_version":"2.9-0ubuntu2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110604.json"}},{"package":{"name":"mxml","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/mxml?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.10-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmxml-bin","binary_version":"2.10-1"},{"binary_name":"libmxml1","binary_version":"2.10-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110604.json"}},{"package":{"name":"mxml","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/mxml?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.12-2","3.1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.1-1","binary_name":"libmxml1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110604.json"}},{"package":{"name":"mxml","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/mxml?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2-1","3.3-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmxml1","binary_version":"3.3-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110604.json"}},{"package":{"name":"mxml","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/mxml?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.1-1","3.3.1-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmxml1","binary_version":"3.3.1-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110604.json"}},{"package":{"name":"mxml","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/mxml?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.1-1build2","4.0.4-6"],"ecosystem_specific":{"binaries":[{"binary_name":"libmxml4","binary_version":"4.0.4-6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110604.json"}},{"package":{"name":"mxml","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/mxml?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.1-1build1","3.3.1-1build2"],"ecosystem_specific":{"binaries":[{"binary_name":"libmxml1","binary_version":"3.3.1-1build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-110604.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:L"},{"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"},{"type":"Ubuntu","score":"medium"}]}
