iPhone v1.1.1 Update
Bluetooth
CVE-ID: CVE-2007-3753
Impact: An attacker within Bluetooth range may be able to cause an unexpected application termination or arbitrary code execution.
Description: An input validation issue exists in the iPhone’s Bluetooth server. By sending maliciously crafted Service Discovery Protocol (SDP) packets to an iPhone with Bluetooth enabled, an attacker may trigger the issue, which may lead to unexpected application termination or arbitrary code execution. This update addresses the issue by performing additional validation of SDP packets. Credit to Kevin Mahaffey and John Hering of Flexilis Mobile Security for reporting this issue.
CVE-ID: CVE-2007-3754
Impact: Checking email over untrusted networks may lead to information disclosure via a man-in-the-middle attack.
Description: When Mail is configured to use SSL for incoming and outgoing connections, it does not warn the user when the identity of the mail server has changed or cannot be trusted. An attacker capable of intercepting the connection may be able to impersonate the user’s mail server and obtain the user’s email credentials or other sensitive information. This update addresses the issue by properly warning when the identity of the remote mail server has changed.
CVE-ID: CVE-2007-3755
Impact: Following a telephone (“tel:”) link in Mail will dial a phone number without confirmation.
Description: Mail supports telephone (“tel:”) links to dial phone numbers. By enticing a user to follow a telephone link in a mail message, an attacker can cause iPhone to place a call without user confirmation. This update addresses the issue by providing a confirmation window before dialling a phone number via a telephone link in Mail. Credit to Andi Baritchi of McAfee for reporting this issue.
Safari
CVE-ID: CVE-2007-3756
Impact: Visiting a malicious website may lead to the disclosure of URL contents.
Description: A design issue in Safari allows a web page to read the URL that is currently being viewed in its parent window. By enticing a user to visit a maliciously crafted web page, an attacker may be able to obtain the URL of an unrelated page. This update addresses the issue through an improved cross-domain security check. Credit to Michal Zalewski of Google Inc. and Secunia Research for reporting this issue.
Safari
CVE-ID: CVE-2007-3757
Impact: Visiting a malicious website may lead to unintended dialling or dialling a different number to the one expected.
Description: Safari supports telephone (“tel:”) links to dial phone numbers. When a telephone link is selected, Safari will confirm that the number should be dialled. A maliciously crafted telephone link may cause a different number to be displayed during confirmation to the one actually dialled. Exiting Safari during the confirmation process may result in unintentional confirmation. This update addresses the issue by properly displaying the number that will be dialled and requiring confirmation for telephone links.

Safari
CVE-ID: CVE-2007-3758
Impact: Visiting a malicious website may lead to cross-site scripting.
Description: A cross-site scripting vulnerability exists in Safari that allows malicious websites to set JavaScript window properties of websites served from a different domain. By enticing a user to visit a maliciously crafted website, an attacker can trigger the issue, resulting in getting or setting the window status and location of pages served from other websites. This update addresses the issue by providing improved access controls on these properties. Credit to Michal Zalewski of Google Inc. for reporting this issue.
Safari
CVE-ID: CVE-2007-3759
Impact: Disabling JavaScript does not take effect until Safari is restarted.
Description: Safari can be configured to enable or disable JavaScript. This preference does not take effect until the next time Safari is restarted. This usually occurs when the iPhone is restarted. This may mislead users into believing that JavaScript is disabled when it is not. This update addresses the issue by applying the new preference prior to loading new web pages.
Safari
CVE-ID: CVE-2007-3760
Impact: Visiting a malicious website may result in cross-site scripting.
Description: A cross-site scripting issue in Safari allows a maliciously crafted website to bypass the same-origin policy using “frame” tags. By enticing a user to visit a maliciously crafted web page, an attacker can trigger the issue, which may lead to the execution of JavaScript in the context of another site. This update addresses the issue by disallowing JavaScript as an “iframe” source and limiting JavaScript in frame tags to the same access as the site from which it was served. Credit to Michal Zalewski of Google Inc. and Secunia Research for reporting this issue.
Safari
CVE-ID: CVE-2007-3761
Impact: Visiting a malicious website may result in cross-site scripting.
Description: A cross-site scripting issue in Safari allows JavaScript events to be associated with the wrong frame. By enticing a user to visit a maliciously crafted web page, an attacker may cause the execution of JavaScript in the context of another site. This update addresses the issue by associating JavaScript events to the correct source frame.
Safari
CVE-ID: CVE-2007-4671
Impact: JavaScript on websites may access or manipulate the contents of documents served over HTTPS.
Description: An issue in Safari allows content served over HTTP to alter or access content served over HTTPS in the same domain. By enticing a user to visit a maliciously crafted web page, an attacker may cause the execution of JavaScript in the context of HTTPS web pages in that domain. This update addresses the issue by limiting access between JavaScript executing in HTTP and HTTPS frames. Credit to Keigo Yamazaki of LAC Co., Ltd. (Little eArth Corporation Co., Ltd.) for reporting this issue.
