Name of the Vulnerable Software and Affected Versions Apache Xerces-C versions 3.0.0 through 3.2.3

Description The issue is related to a use-after-free error in the XML parser, triggered during the scanning of external DTDs. This allows a remote attacker to access confidential information or cause a denial of service. The flaw is associated with incorrect DTD scanning.

Recommendations For Apache Xerces-C versions 3.0.0 through 3.2.3, disable DTD processing to mitigate the issue. This can be done via the DOM using a standard parser feature, or via SAX using the XERCES DISABLE DTD environment variable.
