APPLE-SA-2008-01-15 iPhone v1.1.3 and iPod touch v1.1.3
iPhone v1.1.3 and iPod touch v1.1.3 are now available and address the
following issues:
Foundation
CVE-ID: CVE-2008-0035
Available for: iPhone v1.0 through v1.1.2,
iPod touch v1.1 through 1.1.2
Impact: Accessing a maliciously crafted URL may lead to an
application termination or arbitrary code execution
Description: A memory corruption issue exists in Safari's handling
of URLs. By enticing a user to access a maliciously crafted URL, an
attacker may cause an unexpected application termination or arbitrary
code execution. This update addresses the issue by performing
additional validation of URLs.
Passcode Lock
CVE-ID: CVE-2008-0034
Available for: iPhone v1.0 through v1.1.2
Impact: An unauthorized user may bypass the Passcode Lock and launch
iPhone applications
Description: The Passcode Lock feature is designed to prevent
applications from being launched unless the correct passcode is
entered. An implementation issue in the handling of emergency calls
allows users with physical access to an iPhone to launch an
application without the passcode. This update addresses the issue
through an improved check on the state of the Passcode Lock.
Safari
CVE-ID: CVE-2007-5858
Available for: iPhone v1.0 through v1.1.2,
iPod touch v1.1 through 1.1.2
Impact: Visiting a malicious website may result in the disclosure of
sensitive information
Description: WebKit allows a page to navigate the subframes of any
other page. Visiting a maliciously crafted web page could trigger a
cross-site scripting attack, which may lead to the disclosure of
sensitive information. This update addresses the issue by
implementing a stricter frame navigation policy.
Installation note:
This update is only available through iTunes, and will not appear in
your computer's Software Update application, or in the Apple
Downloads site. Make sure you have an internet connection and have
installed the latest version of iTunes from www.apple.com/itunes/
iTunes will automatically check Apple's update server on its weekly
schedule. When an update is detected, it will download it. When
the iPhone or iPod touch is docked, iTunes will present the user with
the option to install the update. We recommend applying the update
immediately if possible. Selecting "don't install" will present the
option the next time you connect your iPhone or iPod touch.
The automatic update process may take up to a week depending on the
day that iTunes checks for updates. You may manually obtain the
update via the "Check for Update" button within iTunes. After doing
this, the update can be applied when your iPhone or iPod touch is
docked to your computer.
To check that the iPhone or iPod touch has been updated:
* Navigate to Settings
* Select General
* Select About. The version after applying this update will be
"1.1.3 (4A93)" or later
Information will also be posted to the Apple Product Security
web site: http://docs.info.apple.com/article.html?artnum=61798
