Description Adam Mariš 2016-02-08 13:52:14 UTC 
It was found that php_stream_populate_meta_data is not restricted to writing into fields that are not already set, instead php_stream with ops set to php_stream_temp_ops fills the metadata with whatever the user supplies.

Limited integrity impact, unlikely to affect many use cases.  No plan to backport the fix to existing products.
