Title

libxmljs2 namespaces type confusion RCE

Summary

libxmljs2 is vulnerable to a type confusion vulnerability when parsing a specially crafted XML while invoking the namespaces() function (which invokes XmlNode::get_local_namespaces()) on a grand-child of a node that refers to an entity. This vulnerability can lead to denial of service and remote code execution.

Summary

libxmljs2 vulnerable to type confusion when parsing specially crafted XML

Details

libxmljs2 is vulnerable to a type confusion vulnerability when parsing a specially crafted XML while invoking the namespaces() function (which invokes XmlNode::get_local_namespaces()) on a grand-child of a node that refers to an entity. This vulnerability can lead to denial of service and remote code execution.
