http://support.apple.com/kb/HT1222

An email from apple describes an update for the iPhone and iPod Touch
that covers arbitrary code execution and passcode bypass vulnerabilities.

"iPhone OS 3.1.3 and iPhone OS 3.1.3 for iPod touch is now available
and addresses the following:

CoreAudio
CVE-ID: CVE-2010-0036
Available for: iPhone OS 1.0 through 3.1.2,
iPhone OS for iPod touch 1.1 through 3.1.2
Impact: Playing a maliciously crafted mp4 audio file may lead to an
unexpected application termination or arbitrary code execution
Description: A buffer overflow exists in the handling of mp4 audio
files. Playing a maliciously crafted mp4 audio file may lead to an
unexpected application termination or arbitrary code execution. This
issue is addressed through improved bounds checking. Credit to Credit
to Tobias Klein of trapkit.de for reporting this issue.

ImageIO
CVE-ID: CVE-2009-2285
Available for: iPhone OS 1.0 through 3.1.2,
iPhone OS for iPod touch 1.1 through 3.1.2
Impact: Viewing a maliciously crafted TIFF image may lead to an
unexpected application termination or arbitrary code execution
Description: A buffer underflow exists in ImageIO's handling of TIFF
images. Viewing a maliciously crafted TIFF image may lead to an
unexpected application termination or arbitrary code execution. This
issue is addressed through improved bounds checking.

Recovery Mode
CVE-ID: CVE-2010-0038
Available for: iPhone OS 1.0 through 3.1.2,
iPhone OS for iPod touch 1.1 through 3.1.2
Impact: A person with physical access to a locked device may be able
to access the user's data
Description: A memory corruption issue exists in the handling of a
certain USB control message. A person with physical access to the
device could use this to bypass the passcode and access the user's
data. This issue is addressed through improved handling of the USB
control message.

WebKit
CVE-ID: CVE-2009-3384
Available for: iPhone OS 1.0 through 3.1.2,
iPhone OS for iPod touch 1.1 through 3.1.2
Impact: Accessing a maliciously crafted FTP server could result in
an unexpected application termination, information disclosure, or
arbitrary code execution
Description: Multiple input validation issues exist in WebKit's
handling of FTP directory listings. Accessing a maliciously crafted
FTP server may lead to information disclosure, unexpected application
termination, or execution of arbitrary code. This update addresses
the issues through improved parsing of FTP directory listings. Credit
to Michal Zalewski of Google Inc. for reporting these issues.

WebKit
CVE-ID: CVE-2009-2841
Available for: iPhone OS 1.0 through 3.1.2,
iPhone OS for iPod touch 1.1 through 3.1.2
Impact: Mail may load remote audio and video content when remote
image loading is disabled
Description: When WebKit encounters an HTML 5 Media Element pointing
to an external resource, it does not issue a resource load callback
to determine if the resource should be loaded. This may result in
undesired requests to remote servers. As an example, the sender of an
HTML-formatted email message could use this to determine that the
message was read. This issue is addressed by generating resource load
callbacks when WebKit encounters an HTML 5 Media Element."

Installation of updates are only available through iTunes. It may take
up to a week to download, depending on the automatic schedule of your
iTunes.

"You may manually obtain the update via the Check for Updates button
within iTunes. After doing this, the update can be applied when your
iPhone or iPod touch is docked to your computer."

To check if your iPhone has been updated:

'* Navigate to Settings
