CVE-2024-23807 Information

Description

The Apache Xerces C++ XML parser on versions 3.0.0 before 3.2.5 contains a use-after-free error triggered during the scanning of external DTDs.

Users are recommended to upgrade to version 3.2.5 which fixes the issue or mitigate the issue by disabling DTD processing. This can be accomplished via the DOM using a standard parser feature or via SAX using the XERCES_DISABLE_DTD environment variable.

This issue has been disclosed before as CVE-2018-1311 but unfortunately that advisory incorrectly stated the issue would be fixed in version 3.2.3 or 3.2.4.
