If you're running Oracle 8.0.5 on a Unix box, do *not* install and configure the Intellegent Agent option. If you have, find the bin/oratclsh file and REMOVE THE SUID BIT! oratclsh is a Tcl app that provides full access to Tcl. It's also installed as suid root. Running oratclsh gives anyone with even the most modest Tcl knowledge the ability to execute arbitrary Tcl commands *while running as root*! This includes the exec command, which spawns off a subshell (as root) to run any command on the system. Anyone with half a brain is exactly three commands away from full root access. Anyone with a whole brain is exactly *one* command away from full root access. This hole has been verified on both Linux and Solaris with Oracle 8.0.5. It probably exists in all Unix versions of 8.0.5. Whether it exists in later versions is unknown. (I don't believe it exists in 8.0.4, but I can't verify that at the moment) I also don't know if it affects non-Unix versions of 8.0.5. Once again, Intellegent Agent only needs to be *installed* (and the root.sh part of the setup run) to open this hole. The agent does *not* need to be started--just installed.
