APPLE-SA-2007-06-20 Apple TV 1.1

Apple TV 1.1 is now available and, along with its other content,
addresses the following security issue:

CVE-ID: CVE-2007-2386

Available for: Apple TV

Impact: A remote attacker may be able to cause a denial of service or
arbitrary code execution

Description: A buffer overflow vulnerability exists in the UPnP IGD
(Internet Gateway Device Standardized Device Control Protocol) code
used to create Port Mappings on home NAT gateways in the Apple TV
implementation. By sending a maliciously crafted packet, a remote
attacker can trigger the overflow which may lead to an unexpected
application termination or arbitrary code execution. This update
addresses the issue by performing additional validation when
processing UPnP protocol packets. Credit to Michael Lynn of Juniper
Networks for reporting this issue.

Installation note:

The Apple TV device will automatically check Apple's update server on
its weekly schedule.  When an update is detected, it will download
it, verify its signature, and install it.

This process may take up to a week depending on the day that the
Apple TV device checks for updates.  Alternatively, you may manually
update your Apple TV using the TV interface by selecting
Settings > Update Software.

This update is only available directly to the Apple TV, and will not
appear in your computer's Software Update application, or in the
Apple Downloads site.

To check that the Apple TV has been updated, use the TV interface:

* Navigate to Settings
* Select About
* The Software Version after applying this update will be "1.1"
* To exit the About screen to the main menu, press Menu

Information will also be posted to the Apple Product Security
web site:
