Shared-memory connection threats on UNIX

A shared-memory connection provides fast access to a database server if the client and the server are on the same computer, but it poses some security risks. False or nontrusted applications can delete or view message buffers of their own or of other local users. Shared-memory communication is also vulnerable to programming errors if the client application explicitly addresses memory or over-indexes data arrays.

The OSA ensures that the shared-memory connection method is not specified in the configuration file for client/server connections. If the client and the server are on the same computer, a client can connect to a server with a stream-pipe connection or a network-loopback connection.
