CVE-2009-0942: Input Validation
First published: Wed May 13 2009(Updated: )
Help Viewer in Apple Mac OS X 10.4.11 and 10.5 before 10.5.7 does not verify that certain Cascading Style Sheets (CSS) are located in a registered help book, which allows remote attackers to execute arbitrary code via a help: URL that triggers invocation of AppleScript files.
