iTunes 9.2.1 fixes critical hole

iTunes 9.2.1 comes with improvements and a security fix.

A buffer overflow exists in the handling of “itpc:” URLs. Accessing a maliciously crafted “itpc:” URL may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved bounds checking.

The bug fixes are:

• Disables older versions of some incompatible third-party plug-ins
• Addresses minor issues with dragging and dropping items
• Addresses a performance issue when first syncing to some devices with iTunes 9.2
• Addresses an issue upgrading to iOS 4 on an iPhone or iPod touch with encrypted back-ups
• Addresses other issues that improve stability and performance.
