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.
