iPod touch v2.1

  • Application Sandbox

    CVE-ID: CVE-2008-3631

    Available for: iPod touch v2.0 through v2.0.2

    Impact: An application may be able to read another application's files

    Description: The Application Sandbox does not properly enforce access restrictions between third-party applications. This may allow a third-party application to read files in another third-party application's sandbox and lead to the disclosure of sensitive information. This update addresses the issue by enforcing the proper access restrictions between application sandboxes. Credit to Nicolas Seriot of Sen:te and Bryce Cogswell for reporting this issue. This issue does not affect iPod touch versions prior to v2.0.

  • CoreGraphics

    CVE-ID: CVE-2008-1806, CVE-2008-1807, CVE-2008-1808

    Available for: iPod touch v1.1 through v2.0.2

    Impact: Multiple vulnerabilities in FreeType v2.3.5

    Description: Multiple vulnerabilities exist in FreeType v2.3.5, the most serious of which may lead to arbitrary code execution when accessing maliciously crafted font data. This update addresses the issue by incorporating the security fixes from version 2.3.6 of FreeType. Further information is available via the FreeType site at http://www.freetype.org/

  • mDNSResponder

    CVE-ID: CVE-2008-1447

    Available for: iPod touch v1.1 through v2.0.2

    Impact: mDNSResponder is susceptible to DNS cache poisoning and may return forged information

    Description: mDNSResponder provides translation between host names and IP addresses for applications that use its unicast DNS resolution API. A weakness in the DNS protocol may allow a remote attacker to perform DNS cache poisoning attacks. As a result, applications that rely on mDNSResponder for DNS may receive forged information. This update addresses the issue by implementing source port and transaction ID randomization to improve resilience against cache poisoning attacks. Credit to Dan Kaminsky of IOActive for reporting this issue.

  • Networking

    CVE-ID: CVE-2008-3612

    Available for: iPod touch v1.1 through v2.0.2

    Impact: Predictable TCP initial sequence numbers generation may lead to TCP spoofing or session hijacking

    Description: TCP initial sequence numbers are sequentially generated. Predictable initial sequence numbers may allow a remote attacker to create a spoofed TCP connection or insert data into an existing TCP connection. This update addresses the issue by generating random TCP initial sequence numbers.

  • WebKit

    CVE-ID: CVE-2008-3632

    Available for: iPod touch v1.1 through v2.0.2

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

    Description: A use-after-free issue exists in WebKit's handling of CSS import statements. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This update addresses the issue through improved handling of document references.
