Mac OS X Dashboard Arbitrary Widget Injection
------------------------------------------------------------------------
SUMMARY
"Mac OS X is the latest version of the Mac OS, the operating system
software for Macintosh computers. It consists of two main parts: Darwin,
an open source UNIX-like environment which is based on the BSD source tree
and the Mach microkernel, adapted and further developed by Apple Computer
with involvement from independent developers; and a proprietary GUI named
Aqua, developed by Apple."
Combination of Safari and Dashboard in OS X are vulnerable to arbitrary
widget injection, exploiting this vulnerability may lead to arbitrary code
execution and allows malicious attacker to gain full control over the
system.
DETAILS
Vulnerable Systems:
* Mac OS X version 10.4
Immune Systems:
* Mac OS X version 10.4.1 or newer
Dashboard in combination with Safari in Mac OS X contains a flaw that may
allow a remote attacker to inject arbitrary widgets. The issue is
triggered when the 'Open "safe" files after downloading' option in Safari
is enabled. It is possible that the flaw may allow a remote attacker to
create a malicious web page that contains an embedded META tag to trigger
Safari to download a malicious widget, which would be automatically
installed under the /Library/Widgets or ~/Library/Widgets directory
without any user intervention resulting in a loss of integrity.
Workaround:
Disable the 'Open "safe" files after downloading' option in Safari.
