The XML parser in Xerces-C++ before 3.0.0 allows context-dependent attackers to cause a denial of service (stack consumption and crash) via an XML schema definition with a large maxOccurs value, which triggers excessive memory consumption during validation of an XML file.

xerces-c27: Stack overflow when parsing recursive XML structures

Stack consumption vulnerability in validators/DTD/DTDScanner.cpp in Apache Xerces C++ 2.7.0 and 2.8.0 allows context-dependent attackers to cause a denial of service (application crash) via vectors involving nested parentheses and invalid byte values in "simply nested DTD structures," as demonstrated by the Codenomicon XML fuzzing framework.

The XML parser in Xerces-C++ 2.5.0 allows remote attackers to cause a denial of service (CPU consumption) via XML attributes in a crafted XML document.

Apache Xerces C++: Use-after-free on external DTD scan

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.

xerces-c: XML parser contains a use-after-free error triggered during the scanning of external DTDs

The Apache Xerces-C 3.0.0 to 3.2.3 XML parser contains a use-after-free error triggered during the scanning of external DTDs. This flaw has not been addressed in the maintained version of the library and has no current mitigation other than to disable DTD processing. This can be accomplished via the DOM using a standard parser feature, or via SAX using the XERCES_DISABLE_DTD environment variable.

xml: xerces-c hash table collisions CPU usage DoS (oCERT-2011-003)

Apache Xerces-C++ allows remote attackers to cause a denial of service (CPU consumption) via a crafted message sent to an XML service that causes hash table collisions.

xerces-c: Use-after-free in heap on specially crafted XML input

Use-after-free vulnerability in validators/DTD/DTDScanner.cpp in Apache Xerces C++ 3.1.3 and earlier allows context-dependent attackers to have unspecified impact via an invalid character in an XML document.

xerces-c: Stack overflow when parsing deeply nested DTD

Stack-based buffer overflow in Apache Xerces-C++ before 3.1.4 allows context-dependent attackers to cause a denial of service via a deeply nested DTD.

xerces-c: crashes on malformed input

internal/XMLReader.cpp in Apache Xerces-C before 3.1.2 allows remote attackers to cause a denial of service (segmentation fault and crash) via crafted XML data.

HCL BigFix Platform is vulnerable to an integer overflow in xerces-c++ 3.2.3

An integer overflow in xerces-c++ 3.2.3 in BigFix Platform allows remote attackers to cause out-of-bound access via HTTP request.

xerces-c: Null pointer dereference while processing the path to DTD allows denial of service

In Apache Xerces-C XML Parser library before 3.2.1, processing of external DTD paths can result in a null pointer dereference under certain conditions.
