Apple iOS 4.1 fixes security issues
Posted on 09 September 2010.
The iOS 4.1 Software Update is the first major update to iOS 4, bringing Game Center, new iTunes features, high dynamic range photography, and security updates to the iPhone.


Accessibility

A user interface accessibility issue exists in the settings panel for Location Services. VoiceOver does not announce the presence of the location services icon that is shown next to an application that has requested the user's location within the last 24 hours. This issue is addressed by ensuring that VoiceOver announces the presence of the icon.

FaceTime

An issue in the handling of invalid certificates may allow an attacker in a privileged network position to redirect FaceTime calls. This issue is addressed through improved handling of certificates.

ImageIO

A memory corruption issue exists in the handling of TIFF images. Processing a maliciously crafted TIFF image may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved handling of TIFF images.

A buffer overflow exists in the handling of GIF images. Processing a maliciously crafted GIF image may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved bounds checking.

WebKit

A use after free issue exists in WebKit's handling of "foreignObject" elements in SVG documents. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through additional validation of SVG documents.

A type checking issue exists in WebKit's handling of text nodes. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved type checking.

An uninitialized memory access issue exists in WebKit's handling of the ":first-letter" and ":first-line" pseudo-elements in SVG text elements. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed by not rendering ":first-letter" or ":first-line" pseudo-elements in SVG text elements.

A use after free issue exists in WebKit's handling of element focus. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved handling of element focus.

A use after free issue exists in WebKit's handling of "font-face" and "use" elements in SVG documents. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved handling of "font-face" and "use" elements in SVG documents.

A design issue exists in the implementation of the JavaScript execCommand function. A maliciously crafted web page can modify the contents of the clipboard without user interaction. This issue is addressed by only allowing clipboard commands to be executed if initiated by the user.

An implementation issue exists in WebKit's handling of keyboard focus. If the keyboard focus changes during the processing of key presses, WebKit may deliver an event to the newly-focused frame, instead of the frame that had focus when the key press occurred. A maliciously crafted website may be able to manipulate a user into taking an unexpected action, such as initiating a purchase. This issue is addressed by preventing the delivery of key press events if the keyboard focus changes during processing.

A use after free issue exists in WebKit's handling of fonts. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved handling of fonts.

A memory corruption issue exists in WebKit's handling of dynamic modifications to text nodes. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved memory management.

A design issue exists in WebKit's handling of HTTP redirects. When a form submission is redirected to a website that also does a redirection, the information contained in the submitted form may be sent to the third site. This issue is addressed through improved handling of HTTP redirects.

A memory corruption issue exists in WebKit's rendering of inline elements. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved bounds checking.

A double free issue exists in WebKit's rendering of inline elements. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved memory management.

A memory corruption issue exists in WebKit's handling of CSS counters. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved memory management.

A memory corruption issue exists in WebKit's handling of floating elements in SVG documents. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved memory management.

A signedness issue exists in WebKit's handling of JavaScript arrays. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved handling of JavaScript array indices.

A memory corruption issue exists in WebKit's handling of "use" elements in SVG documents. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved handling of "use" elements in SVG documents.

A use after free issue exists in WebKit's handling of selections. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved handling of selections.

A memory corruption issue exists in WebKit's rendering of HTML object outlines. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved memory management.

A memory corruption issue exists in WebKit's handling of form menus. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is fixed through improved handling of form menus.

A use after free issue exists in WebKit's handling of scrollbars. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved memory management.
