restrictions and denial of service.
I. Description
Apple Security Update 2006-004 resolves a number of vulnerabilities
affecting Mac OS X, OS X Server, Safari web browser, Mail, and other
products. Further details are available in the individual
Vulnerability Notes.
This security update addresses vulnerabilities in a range of different
components, including the handling of a number of different image file
formats, ZIP archive files, and HTML web pages, among others.
II. Impact
The impacts of these vulnerabilities vary. For information about
specific impacts, please see the Vulnerability Notes. Potential
consequences include remote execution of arbitrary code or commands,
bypass of security restrictions, and denial of service.
III. Solution
Install an update
Install Apple Security Update 2006-004. This and other updates are
available via Apple Update.
Workaround
Disable "Open 'safe' files after downloading"
For additional protection, disable the Safari web browser option to
"Open 'safe' files after downloading," as specified in "Securing Your
Web Browser."
Note that this workaround will not mitigate all of the vulnerabilities
described in the Apple Security Update, only those which are
exacerbated by the default behavior of the Safari web browser.
