Serious Linux Kernel security hole

(Other stories by Steven J. Vaughan-Nichols)

"Linux has security problems like any other operating system. Most of them aren't that big a deal though. Many of the more serious ones require local user access to cause any real trouble, and except for Linux desktop users that's not a real concern. The latest Linux security problem with Reliable Datagram Sockets (RDS) though is a real problem.

"RDS is an Oracle creation. It's used for sending multiple messages from a single network socket to multiple end-points. The point of RDS is that you can use it to keep inter-process communication (IPC) going without timeouts when a system is running under very heavy loads. Thus, you're most likely to be using RDS if you're running a mission-critical DBMS server or a Linux, Apache, MySQL, PHP/Python/Perl (LAMP) stack application."
