CVE-2024-23807 – Apache Xerces C++: Use-after-free on external DTD scan

https://notcve.org/view.php?id=CVE-2024-23807

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. El analizador XML Apache Xerces C++ en las versiones 3.0.0 anteriores a la 3.2.5 contiene un error de use-after-free que se activa durante el escaneo de DTD externos. Se recomienda a los usuarios actualizar a la versión 3.2.5, que soluciona el problema, o mitigarlo desactivando el procesamiento de DTD. Esto se puede lograr a través del DOM usando una función de analizador estándar, o vía SAX usando la variable de entorno XERCES_DISABLE_DTD. • https://github.com/apache/xerces-c/pull/54 https://lists.apache.org/thread/c497tgn864tsbm8w0bo3f0d81s07zk9r • CWE-416: Use After Free •
