Following reports this week of a potential Android ‘Jailbreak’, Google have announced a new update to fix the vulnerability.
Update RC 30 will apparently remedy the exploit that enables users to gain root access on their G1 handsets via Android’s telnetd service.
We’ve been notified of this issue (Jailbreaking of Android) and have developed a fix. We’re currently working with our partners to push the fix out and updating the open source code base to reflect these changes.
The new update is expected to be pushed to handsets over the next few days.
