Data Security
Available for: iOS 3.0 through 4.3.5 for iPhone 3GS and iPhone 4, iOS 3.1 through 4.3.5 for iPod touch (3rd generation) and later, iOS 3.2 through 4.3.5 for iPad
Impact: Support for X.509 certificates with MD5 hashes may expose users to spoofing and information disclosure as attacks improve
Description: Certificates signed using the MD5 hash algorithm were accepted by iOS. This algorithm has known cryptographic weaknesses. Further research or a misconfigured certificate authority could have allowed the creation of X.509 certificates with attacker controlled values that would have been trusted by the system. This would have exposed X.509 based protocols to spoofing, man in the middle attacks, and information disclosure. This update disables support for an X.509 certificate with an MD5 hash for any use other than as a trusted root certificate.
CVE-ID
CVE-2011-3427
-
Data Security
Available for: iOS 3.0 through 4.3.5 for iPhone 3GS and iPhone 4, iOS 3.1 through 4.3.5 for iPod touch (3rd generation) and later, iOS 3.2 through 4.3.5 for iPad
Impact: An attacker could decrypt part of a SSL connection
Description: Only the SSLv3 and TLS 1.0 versions of SSL were supported. These versions are subject to a protocol weakness when using block ciphers. A man-in-the-middle attacker could have injected invalid data, causing the connection to close but revealing some information about the previous data. If the same connection was attempted repeatedly the attacker may eventually have been able to decrypt the data being sent, such as a password. This issue is addressed by adding support for TLS 1.2.

Safari
Available for: iOS 3.0 through 4.3.5 for iPhone 3GS and iPhone 4, iOS 3.1 through 4.3.5 for iPod touch (3rd generation) and later, iOS 3.2 through 4.3.5 for iPad
Impact: Opening maliciously crafted files on certain websites may lead to a cross-site scripting attack
