Secunia

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

1) An error in CoreAudio when processing sample size table entries of AAC and MP3 files can be exploited to cause a heap-based buffer overflow and potentially execute arbitrary code.

2) An error in Exchange Support exists due to the "Require Passcode" setting not being affected by the "Maximum inactivity time lock" setting. This may lead to a time window, regardless of the Maximum inactivity time lock" setting, in which a person with physical access to the device is able to use the Exchange services.

3) A security issue exists in MobileMail due to deleted mails being accessible via Spotlight search. This can be exploited by malicious people with physical access to the device to disclose potentially sensitive information.

4) An unspecified error exists in the Recovery Mode command parsing. This can be exploited by a person with physical access to a device to cause a heap-based buffer overflow and e.g. gain access to a locked device.

5) A NULL pointer dereference error within the handling of SMS arrival notifications can be exploited to cause a service interruption.

6) An error in the handling of passwords in UIKit can be exploited by a person with physical access to a device to disclose a password.

7) Safari includes the user name and password in the "Referer" header, which can lead to the exposure of sensitive information.

8) Two vulnerabilities in WebKit can be exploited by malicious people to conduct cross-site scripting attacks or potentially compromise a user's system.
