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
SOLUTION:
Update to iPhone OS 2.2 or iPhone OS for iPod touch 2.2 (downloadable
