Name of the Vulnerable Software and Affected Versions Apache Xerces-C XML Parser library versions prior to 3.2.1

Description The issue is related to the incorrect processing of external DTD paths in the Apache Xerces-C XML Parser library, which can lead to a null pointer dereference under certain conditions. This can potentially allow a remote attacker to cause a denial of service.

Recommendations For versions prior to 3.2.1, update to version 3.2.1 or later to resolve the issue. As a temporary workaround, consider restricting the processing of external DTD paths until a patch is available.
