    Description: Fraudulent certificates were issued by multiple certificate authorities operated by DigiNotar. This issue is addressed by removing DigiNotar from the list of trusted root certificates, from the list of Extended Validation (EV) certificate authorities, and by configuring default system trust settings so that DigiNotar's certificates, including those issued by other authorities, are not trusted.

  • 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

    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
