A newly discovered iPhone exploit could help developers find another way to run third-party applications on Apple's device.
Posters to the Hackintosh forums have discovered that Mobile Safari on both the Touch and the iPhone suffer from a one year old TIFF buffer overflow exploit that could lead to a jailbreak for the devices.
Essentially, opening a carefully crafted TIFF image will crash Mobile Safari, causing a buffer overflow and allow for arbitrary code execution. A poster to the forums writes "This same exploit was used more than 1.5 years ago to crack the PSP firmware." This could theoretically lead to a new "jailbreak" process that would again allow third-party applications to be written to iPhones running the most recent firmware 1.1.1 release that disabled the functionality for all those who updated.
