Description Avinash Hanwate 2022-05-02 06:16:52 UTC

This affects all versions of package libxmljs. When invoking the libxmljs.parseXml function with a non-buffer argument the V8 code will attempt invoking the .toString method of the argument. If the argument's toString value is not a Function object V8 will crash.
