iOS 3.1 and iOS 3.1.1 for iPod touch

  • CoreAudio

    CVE-ID: CVE-2009-2206

    Available for: iOS 1.0 through 3.0.1, iOS for iPod touch 1.1 through 3.0

    Impact: Opening a maliciously crafted AAC or MP3 file may lead to an unexpected application termination or arbitrary code execution

    Description: A heap buffer overflow exists in the handling of AAC or MP3 files. Opening a maliciously crafted AAC or MP3 file may lead to an unexpected application termination or arbitrary code execution. This update addresses the issue through improved bounds checking.

  • Exchange Support

    CVE-ID: CVE-2009-2794

    Available for: iOS 1.0 through 3.0.1, iOS for iPod touch 1.1 through 3.0

    Impact: A person with physical access to a device may be able to use it after the timeout period specified by an Exchange administrator

    Description: iOS provides the ability to communicate via services provided by a Microsoft Exchange server. An administrator of an Exchange server has the ability to specify a "Maximum inactivity time lock" setting. This requires the user to reenter their passcode after the expiration of the inactivity time in order to use the Exchange services. iOS allows a user to specify a "Require Passcode" setting that may extend up to 4 hours. The "Require Passcode" setting is not affected by the "Maximum inactivity time lock" setting. If the user has "Require Passcode" set to a value higher than the "Maximum inactivity time lock" setting, this would allow a window of time for a person with physical access to use the device, including Exchange services. This update addresses the issue by disabling user choices for "Require Passcode" values greater than the "Maximum inactivity time lock" setting. This issue only affects iOS 2.0 and later, and iOS for iPod touch 2.0 and later.

  • MobileMail

    CVE-ID: CVE-2009-2207

    Available for: iOS 1.0 through 3.0.1, iOS for iPod touch 1.1 through 3.0

    Impact: Deleted email messages may still be visible through a Spotlight search

    Description: Spotlight finds and allows access to deleted messages in Mail folders on the device. This would allow a person with access to the device to view the deleted messages. This update addresses the issue by not including the deleted email in the Spotlight search result. This issue only affects iOS 3.0, iOS 3.0.1, and iOS for iPod touch 3.0.

  • Recovery Mode

    CVE-ID: CVE-2009-2795

    Available for: iOS 1.0 through 3.0.1, iOS for iPod touch 1.1 through 3.0

    Impact: A person with physical access to a locked device may be able to access the user's data

    Description: A heap buffer overflow exists in Recovery Mode command parsing. This may allow another person with physical access to the device to bypass the passcode, and access the user's data. This update addresses the issue through improved bounds checking.

  • Telephony

    CVE-ID: CVE-2009-2815

    Available for: iOS 1.0 through 3.0.1

    Impact: Receiving a maliciously crafted SMS message may lead to an unexpected service interruption

    Description: A null pointer dereference issue exists in the handling of SMS arrival notifications. Receiving a maliciously crafted SMS message may lead to an unexpected service interruption.

    Available for: iOS 1.0 through 3.0.1, iOS for iPod touch 1.1 through 3.0

    Impact: Passwords may be made visible

    Description: When a character in a password is deleted, and the deletion is undone, the character is briefly made visible. This may allow a person with physical access to the device to read a password, one character at a time. This update addresses the issue by preventing the character from being made visible. This issue only affects iOS 3.0 and iOS 3.0.1. Credit to Abraham Vegh for reporting this issue.

  • WebKit

    CVE-ID: CVE-2009-2797

    Available for: iOS 1.0 through 3.0.1, iOS for iPod touch 1.1 through 3.0

    Impact: User names and passwords in URLs may be disclosed to linked sites

    Description: Safari includes the user name and password from the original URL in the referer header. This may lead to the disclosure of sensitive information. This update addresses the issue by not including user names and passwords in referer headers. Credit to James A. T. Rice of Jump Networks Ltd for reporting this issue.

  • WebKit

    CVE-ID: CVE-2009-1725

    Available for: iOS 1.0 through 3.0.1, iOS for iPod touch 1.1 through 3.0

    Impact: Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution

  • WebKit

    CVE-ID: CVE-2009-2199

    Available for: iOS 1.0 through 3.0.1, iOS for iPod touch 1.1 through 3.0

    Impact: Look-alike characters in a URL could be used to masquerade a website

    Description: The International Domain Name (IDN) support and Unicode fonts embedded in Safari could be used to create a URL which contains look-alike characters. These could be used in a malicious website to direct the user to a spoofed site that visually appears to be a legitimate domain. This update addresses the issue by supplementing WebKit's list of known look-alike characters. Look-alike characters are rendered in Punycode in the address bar.
