  • CoreTypes

    CVE-ID: CVE-2008-4234

    Available for: Mac OS X v10.5 through v10.5.5, Mac OS X Server v10.5 through v10.5.5

    Impact: Attempting to launch unsafe downloaded content may not lead to a warning

Applications such as Safari and others use Download Validation to help warn users prior to launching files marked as potentially unsafe. This update adds to the list of potentially unsafe types. It adds the content type for files that have executable permissions and no specific application association. These files are potentially unsafe as they will launch in Terminal and their content will be executed as commands. While these files are not automatically launched, if manually opened they could lead to the execution of arbitrary code. This issue does not affect systems prior to Mac OS X v10.5.
