NVD Description

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

The IPv6 branch of the FastCGI client access check compares only the first 12 bytes of a 16-byte IPv6 address, so listen.allowed_clients matches on a /96 prefix instead of the exact address. An attacker who can source an address sharing the first 96 bits with an allowed one passes the check and reaches the FastCGI endpoint.
