Daniel Knoppel reports:

+
It was discovered by the SUSE security team that it was possible, + in some cases, for clients to overwrite headers set by the server, + resulting in a medium level security issue. CVE-2015-7519 has been + assigned to this issue.
+
Affected use-cases:
+
Header overwriting may occur if all of the following conditions are met:
+
+
Apache integration mode, or standalone+builtin engine without + a filtering proxy
+
Ruby or Python applications only (Passenger 5); or any + application (Passenger 4)
+
The app depends on a request header containing a dash (-)
+
The header is supposed to be trusted (set by the server)
+
The client correctly guesses the header name
+
+
This vulnerability has been fixed by filtering out client headers + that do not consist of alphanumeric/dash characters (Nginx already + did this, so Passenger+Nginx was not affected). If your application + depends on headers that don't conform to this, you can add a + workaround in Apache specifically for those to convert them to a + dash-based format.
