NVD Description

Note: Versions mentioned in the description apply only to the upstream php-ffi package and not the php-ffi package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

When the HTTP stream wrapper follows a redirect and the response carries a Location header with an empty value, the redirect code reads one byte past the end of the heap buffer holding the location. The value of that out-of-bounds byte decides which redirect target is built, so a malicious server controls whether the client is sent to the host root or to the current directory.
