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:

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.
