TITLE:
Apple iPhone Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA26983

VERIFY ADVISORY:
http://secunia.com/advisories/26983/

CRITICAL:
Moderately critical

IMPACT:
Hijacking, Security Bypass, Cross Site Scripting, Exposure of
sensitive information, DoS, System access

WHERE:
>From remote

OPERATING SYSTEM:
Apple iPhone 1.x
http://secunia.com/product/15128/

DESCRIPTION:
Some vulnerabilities, security issues, and a weakness have been
reported in the Apple iPhone, which can be exploited by malicious
people to conduct cross-site scripting attacks, disclose sensitive
information, bypass certain security restrictions, cause a DoS
(Denial of Service), or to compromise a vulnerable system.

1) An input validation error when handling SDP (Service Discovery
Protocol) packets exists in the iPhone's Bluetooth server. This can
be exploited by an attacker in Bluetooth range to cause the
application to crash or to execute arbitrary code by sending
specially crafted SDP packets.

Successful exploitation requires that Bluetooth is enabled.

2) The problem is that users are not notified about changes of mail
servers' identities when Mail is configured to use SSL for incoming
and outgoing connections. This can be exploited e.g. to impersonate
the user's mail server and obtain the user's email credentials.

Successful exploitation requires a MitM (Man-in-the-Middle) attack.

3) It is possible to cause the iPhone to call a phone number without
user confirmation by enticing a user to follow a "tel:" link in a
mail message.

4) An error in Safari in the handling of new browser windows can be
exploited to disclose the URL of an unrelated page.

For more information see vulnerability #2 in:
SA23893

5) An error in Safari in the handling of "tel:" links can be
exploited to cause the iPhone to dial a different number than the one
being displayed in the confirmation dialog. Exiting Safari during the
confirmation process may result in unintentional confirmation.

6) An error in Safari can be exploited to set Javascript window
properties of pages served from other websites when a malicious web
site is viewed.

7) Disabling Javascript in Safari does not take effect until Safari
is restarted.

8) An error in Safari allows a malicious website to bypass the
same-origin policy using "frame" tags. This can be exploited to
execute Javascript code in the context of another site when a user
visits a malicious web page.

9) An error in Safari allows Javascript events to be associated with
the wrong frame. This can be exploited to execute Javascript code in
context of another site when a user visits a malicious web page.

10) An error in Safari allows content served over HTTP to alter or
access content served over HTTPS in the same domain. This can be
exploited to execute Javascript code in context of HTTPS web pages in
that domain when a user visits a malicious web page.

SOLUTION:
Update to version 1.1.1 (downloadable and installable via iTunes).
