The Apache Xerces is vulnerable to use-after-free. The vulnerability is due to improper handling of memory, leading to potential arbitrary code execution or denial of service. As a remedy, it is recommended to disable DTD processing, either through DOM parser features or by setting the XERCES_DISABLE_DTD environment variable.
