Apple Mac OS X Safari 2.0.3 Vulnerability: A vulnerability exists in Safari 2.0.3 (417.9.2) and perhaps in prior versions which causes the operating system to slow down SRCOD (Spinning Rainbow Cursor Of Death), and therefore, it’s not possible to launch any applications like Terminal to kill the process. After several minutes Safari crashes.
