[REG: 6.3->6.4] wasm: Use after free due to pointer to temporary data being used

    XMLWordPrintable

Details

    • WebAssembly

    Description

      Looks like pointer to data held by a temporary object is begin stored here, which renders WebSockets unusable:

       attr->url = url.toString(QUrl::FullyEncoded).toUtf8().constData();
