A vulnerability has been identified in PHP, which could be exploited by attackers to execute arbitrary commands. This flaw is due to a stack overflow error in the "create_named_pipe()" [libmysql.c] function that does not properly handle an overly long named pipe string passed to the "server" parameter of the "mysql_connect()" function, which could be exploited by attackers who can call a specially crafted "mysql_connect()" function to execute arbitrary commands on a vulnerable server.
