Research In Motion provided a system update to the BlackBerry PlayBook tablet late Tuesday. According to the changelog, the primary purpose of the update was to plug a security hole being exploited by the Dingleberry Playbook jailbreak tool.
The log said that version 18.104.22.16867, which is only 5 MB in size, “offers support for Flash 10.3 and updates to Adobe AIR to support developers in addition to DST and security fixes.”
Researchers had recently released a tool–called Dingleberry–that unlocks the PlayBook, a first for RIM’s tablet, which included government-grade security features. Once unlocked, PlayBook users are granted access to the entire PlayBook codebase, allowing them to do a lot more with it than through the generally available tools.
