Normally, applications cannot intercept events when secure event input is enabled. However, if "Enable access for assistive devices" is on, Quartz Event Services can be used to intercept events even when secure event input is enabled. This update addresses the issue by filtering events when secure event input is enabled. This issue does not affect systems prior to Mac OS X v10.4. Credit to Damien Bobillot for reporting this issue.

  • Finder

    CVE-ID: CVE-2006-1448

    Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.6, Mac OS X Server v10.4.6

    Impact: Launching an Internet Location item may lead to arbitrary code execution

    Description: Internet Location items are simple URL containers which may reference http://, ftp://, and file:// URLs, as well as a few other URL schemes. These different types of Internet Location items are visually distinct, and meant to be safe to explicitly launch. However, the scheme of the URL may be different than the Internet Location type. As a result, an attacker may be able to convince a user to launch a supposedly benign item (such as a Web Internet Location, http://), with the result that some other URL scheme is actually used. In certain circumstances, this may lead to arbitrary code execution. This update addresses the issues by restricting the URL scheme based on the Internet Location type.
