In addition to releasing iOS 4.3.2 for iPhone 4 and 3GS, iPad and iPad 2, and iPod touch (3rd and 4th generation), Apple also released iOS 4.2.7 for the CDMA version of iPhone 4, which includes the Verizon version of the device. Apple’s patch notes for the release simply say that it, “Contains the latest security updates.”
Apple hasn’t posted this particular update to its security site, but it includes the following security fixes:
- Certificate Trust Policy
Available for: iOS 4.2.5 through 4.2.6 for iPhone 4 (CDMA)
Impact: An attacker with a privileged network position may intercept user credentials or other sensitive information
Description: Several fraudulent SSL certificates were issued by a Comodo affiliate registration authority. This may allow a man-in-the- middle attacker to redirect connections and intercept user credentials or other sensitive information. This issue is addressed by blacklisting the fraudulent certificates. Note: For Mac OS X systems, this issue is addressed with Security Update 2011-002. For Windows systems, Safari relies on the certificate store of the host operating system to determine if an SSL server certificate is trustworthy. Applying the update described in Microsoft Knowledge Base Article 2524375 will cause Safari to regard these certificates as untrusted.
