A new firmware is now available for the iPhone and iPod touch. The new update is all about bug fixes and security, as Apple states on it’s info page regarding this update.
The fixes include:

  • Playing a maliciously crafted mp4 audio file may lead to an unexpected application termination or arbitrary code execution.
  • Viewing a maliciously crafted TIFF image may lead to an unexpected application termination or arbitrary code execution; a person with physical access to a locked device may be able to access the user’s data.
  • Accessing a maliciously crafted FTP server could result in an unexpected application termination, information disclosure, or arbitrary code execution.
  • Mail may load remote audio and video content when remote image loading is disabled

The update is available to download now via iTunes on Mac or PC.
