{"id":"ALPINE-CVE-2025-49794","details":"A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the \u003csch:name path=\"...\"/\u003e schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program's crash using libxml or other possible undefined behaviors.","modified":"2025-12-03T22:59:38.618982Z","published":"2025-06-16T16:15:18.997Z","upstream":["CVE-2025-49794"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2025-49794"}],"affected":[{"package":{"name":"libxml2","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/libxml2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.13.9-r0"}]}],"versions":["2.10.0-r0","2.10.1-r0","2.10.2-r0","2.10.2-r1","2.10.3-r0","2.10.3-r1","2.10.3-r2","2.10.4-r0","2.10.4-r1","2.10.4-r2","2.11.0-r0","2.11.0-r1","2.11.0-r2","2.11.0-r3","2.11.1-r0","2.11.2-r0","2.11.3-r0","2.11.3-r1","2.11.3-r2","2.11.4-r0","2.11.5-r0","2.11.6-r0","2.12.3-r0","2.12.4-r0","2.12.5-r0","2.12.6-r0","2.12.6-r1","2.12.6-r2","2.12.7-r0","2.12.8-r0","2.13.4-r0","2.13.4-r1","2.13.4-r2","2.13.4-r3","2.13.4-r4","2.13.4-r5","2.13.4-r6","2.7.2-r0","2.7.3-r0","2.7.6-r0","2.7.6-r1","2.7.6-r2","2.7.6-r3","2.7.7-r0","2.7.7-r1","2.7.7-r2","2.7.7-r3","2.7.7-r4","2.7.8-r0","2.7.8-r1","2.7.8-r2","2.7.8-r4","2.7.8-r5","2.7.8-r6","2.7.8-r7","2.7.8-r8","2.8.0-r0","2.8.0-r1","2.9.0-r0","2.9.0-r1","2.9.0-r2","2.9.0-r3","2.9.1-r0","2.9.1-r1","2.9.1-r2","2.9.10-r0","2.9.10-r1","2.9.10-r2","2.9.10-r3","2.9.10-r4","2.9.10-r5","2.9.10-r6","2.9.10-r7","2.9.12-r0","2.9.12-r1","2.9.12-r2","2.9.12-r3","2.9.13-r0","2.9.14-r0","2.9.14-r1","2.9.2-r0","2.9.2-r1","2.9.2-r2","2.9.3-r0","2.9.4-r0","2.9.4-r1","2.9.4-r2","2.9.4-r3","2.9.4-r4","2.9.5-r0","2.9.6-r0","2.9.6-r2","2.9.7-r0","2.9.7-r1","2.9.8-r0","2.9.8-r1","2.9.8-r2","2.9.9-r0","2.9.9-r1","2.9.9-r2","2.9.9-r3"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-49794.json"}},{"package":{"name":"libxml2","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/libxml2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.13.9-r0"}]}],"versions":["2.10.0-r0","2.10.1-r0","2.10.2-r0","2.10.2-r1","2.10.3-r0","2.10.3-r1","2.10.3-r2","2.10.4-r0","2.10.4-r1","2.10.4-r2","2.11.0-r0","2.11.0-r1","2.11.0-r2","2.11.0-r3","2.11.1-r0","2.11.2-r0","2.11.3-r0","2.11.3-r1","2.11.3-r2","2.11.4-r0","2.11.5-r0","2.11.6-r0","2.12.3-r0","2.12.4-r0","2.12.5-r0","2.12.6-r0","2.12.6-r1","2.12.6-r2","2.12.7-r0","2.12.8-r0","2.13.4-r0","2.13.4-r1","2.13.4-r2","2.13.4-r3","2.13.6-r0","2.13.7-r0","2.13.7-r1","2.13.8-r0","2.7.2-r0","2.7.3-r0","2.7.6-r0","2.7.6-r1","2.7.6-r2","2.7.6-r3","2.7.7-r0","2.7.7-r1","2.7.7-r2","2.7.7-r3","2.7.7-r4","2.7.8-r0","2.7.8-r1","2.7.8-r2","2.7.8-r4","2.7.8-r5","2.7.8-r6","2.7.8-r7","2.7.8-r8","2.8.0-r0","2.8.0-r1","2.9.0-r0","2.9.0-r1","2.9.0-r2","2.9.0-r3","2.9.1-r0","2.9.1-r1","2.9.1-r2","2.9.10-r0","2.9.10-r1","2.9.10-r2","2.9.10-r3","2.9.10-r4","2.9.10-r5","2.9.10-r6","2.9.10-r7","2.9.12-r0","2.9.12-r1","2.9.12-r2","2.9.12-r3","2.9.13-r0","2.9.14-r0","2.9.14-r1","2.9.2-r0","2.9.2-r1","2.9.2-r2","2.9.3-r0","2.9.4-r0","2.9.4-r1","2.9.4-r2","2.9.4-r3","2.9.4-r4","2.9.5-r0","2.9.6-r0","2.9.6-r2","2.9.7-r0","2.9.7-r1","2.9.8-r0","2.9.8-r1","2.9.8-r2","2.9.9-r0","2.9.9-r1","2.9.9-r2","2.9.9-r3"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-49794.json"}},{"package":{"name":"libxml2","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/libxml2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.13.9-r0"}]}],"versions":["2.10.0-r0","2.10.1-r0","2.10.2-r0","2.10.2-r1","2.10.3-r0","2.10.3-r1","2.10.3-r2","2.10.4-r0","2.10.4-r1","2.10.4-r2","2.11.0-r0","2.11.0-r1","2.11.0-r2","2.11.0-r3","2.11.1-r0","2.11.2-r0","2.11.3-r0","2.11.3-r1","2.11.3-r2","2.11.4-r0","2.11.5-r0","2.11.6-r0","2.12.3-r0","2.12.4-r0","2.12.5-r0","2.12.6-r0","2.12.6-r1","2.12.6-r2","2.12.7-r0","2.12.8-r0","2.13.4-r0","2.13.4-r1","2.13.4-r2","2.13.4-r3","2.13.6-r0","2.13.7-r0","2.13.7-r1","2.13.8-r0","2.7.2-r0","2.7.3-r0","2.7.6-r0","2.7.6-r1","2.7.6-r2","2.7.6-r3","2.7.7-r0","2.7.7-r1","2.7.7-r2","2.7.7-r3","2.7.7-r4","2.7.8-r0","2.7.8-r1","2.7.8-r2","2.7.8-r4","2.7.8-r5","2.7.8-r6","2.7.8-r7","2.7.8-r8","2.8.0-r0","2.8.0-r1","2.9.0-r0","2.9.0-r1","2.9.0-r2","2.9.0-r3","2.9.1-r0","2.9.1-r1","2.9.1-r2","2.9.10-r0","2.9.10-r1","2.9.10-r2","2.9.10-r3","2.9.10-r4","2.9.10-r5","2.9.10-r6","2.9.10-r7","2.9.12-r0","2.9.12-r1","2.9.12-r2","2.9.12-r3","2.9.13-r0","2.9.14-r0","2.9.14-r1","2.9.2-r0","2.9.2-r1","2.9.2-r2","2.9.3-r0","2.9.4-r0","2.9.4-r1","2.9.4-r2","2.9.4-r3","2.9.4-r4","2.9.5-r0","2.9.6-r0","2.9.6-r2","2.9.7-r0","2.9.7-r1","2.9.8-r0","2.9.8-r1","2.9.8-r2","2.9.9-r0","2.9.9-r1","2.9.9-r2","2.9.9-r3"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-49794.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H"}]}
