CVE Reference(s):

Description


Some weaknesses, security issues, and vulnerabilities have been reported in Apple iPhone and iPod touch, which can be exploited by malicious people to bypass certain security restrictions, disclose potential sensitive information, conduct spoofing attacks, to cause a DoS (Denial of Service), or potentially compromise a user's system.

1) A vulnerability in CoreGraphics can potentially be exploited to compromise a vulnerable system.

For more information see vulnerability #3 in:
SA31326

2) Several vulnerabilities in the processing of TIFF images can potentially be exploited to execute arbitrary code.

For more information:
SA31610

3) An error in the processing of TIFF images can cause a device reset.

4) An unspecified error can result in the encryption level for PPTP VPN connections to be lower than expected.

5) A signedness error in the Office Viewer component can potentially be exploited to execute arbitrary code via a specially crafted Microsoft Excel file.

This is related to vulnerability #10 in:
SA32222

6) A weakness exists in the handling of emergency calls, which can be exploited to bypass the Passcode lock and call arbitrary numbers when physical access to the device is provided.

7) A weakness causes the Passcode lock not to be restored properly.

8) A security issue can result in the content of an SMS message being displayed when the message arrives while the emergency call screen is shown.

9) An error in Safari when handling HTML table elements can be exploited to cause a memory corruption and potentially execute arbitrary code when a user visits a specially crafted web site.

10) An error in Safari when handling embedded iframe elements can be exploited to spoof the user interface via content being displayed outside its boundaries.

11) An error exists in Safari when launching an application while a call approval dialog is shown. This can be exploited to call an arbitrary number without user interaction. It is also possible to block the user's ability to cancel the call.

12) An error in Webkit can be exploited to disclose potentially sensitive data from form fields, although the "Autocomplete" feature is disabled.

This is related to vulnerability #8 in:
SA32706
