Description Zack Miele 2023-07-13 16:47:22 UTC 
An issue was discovered in Qt before 5.15.15, 6.x before 6.2.10, and 6.3.x through 6.5.x before 6.5.3. There are infinite loops in recursive entity expansion.

https://codereview.qt-project.org/c/qt/qtbase/+/488960

QXmlStreamReader accepted multiple DOCTYPE elements, containing DTD fragments in the XML prolog, and in the XML body. Well-formed but invalid XML files - with multiple DTD fragments in prolog and body, combined with recursive entity expansions - have caused infinite loops in QXmlStreamReader.
