{"id":"AZL-100941","summary":"CVE-2026-74860 affecting package libxml2 2.11.5-10","details":"A flaw was found in libxml2 with Python bindings enabled. A remote attacker could exploit this vulnerability by providing a specially crafted XML document containing a Document Type Definition (DTD) with enumerated attribute values. This triggers a double-free error in the SAX attributeDecl callback handler, where a string is freed twice. This flaw can lead to a denial of service (DoS) due to a reproducible crash in Python applications using the libxml2 SAX bindings.","modified":"2026-09-16T06:39:01Z","published":"2026-09-08T12:16:58Z","upstream":["CVE-2026-74860"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74860"}],"affected":[{"package":{"name":"libxml2","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/libxml2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.11.5-10"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-100941.json"}}],"schema_version":"1.9.0"}
