Owners of the Google Android-based T-Mobile have begun receiving a software update that fixes a Google Android flaw that security researchers found last week.

As well as the fix to the browser vulnerability, the update included a couple of other minor changes, said Michael Kirkland, a Google spokesman.

Google worked with T-Mobile USA, the only operator selling the device, to push the update out to users. The T-Mobile G1 went on sale in the UK last week, and T-Mobile has not disclosed how many have sold so far.

Researchers at Independent Security Evaluators revealed earlier this week that they discovered that Android, Google's open-source software that is currently only running on HTC's G1 handset, is based on outdated open-source components that do not include a fix to a previously known vulnerability.

On a web page for ISE, Charlie Miller, Mark Daniel and Jake Honoroff wrote that they wouldn't say much about the vulnerability until Google fixes it. However, they said that Android users who visit malicious websites may find their sensitive information stolen. That's because an attacker could access any information the site uses, including saved passwords, information entered into a web application form and cookies.

The researchers also said, however, that the impact of the attack is limited because of Android's security architecture. An attacker can't, for example, control functions of the phone such as the dialler.
