I’ve been waiting since last week for iTunes to be updated to support the new iPhone, but along with making the software ready for the iPhone, there are some security issues that this new version of iTunes fixes. Apple has released iTunes 9.2 for Windows systems to address multiple vulnerabilities affecting the ColorSync, ImageIO, and WebKit packages. These vulnerabilities may allow an attacker to execute malicious code on your system or cause a denial-of-service attack.
I recommend that if you have iTunes on your computer that you update it as soon as possible. For more information, please check out Apple’s support documentation located here
