Description
When
ErrorHandlerrenders an exception HTML page, it uses un-escaped properties from the related Exception class to render the stacktrace. The security issue comes from the fact that the stacktraces were also displayed in non-debugenvironments.Resolution
The
ErrorHandlerclass now escapes all properties coming from the related Exception, and the stacktrace is not displayed anymore in non-debugenvironments.The patches for this issue are available here and here for branch 4.4.
