An Android security flaw has been identified which, if exploited, could allow unauthorized access to data saved on a user's memory card and, in some cases, on the device's own storage. Spotted by Thomas Cannon
, there are certain limitations to the exploit - hackers must know the name of the files they wish to steal, not terribly difficult if you're dealing with system-named files like photos - but already the Android security team are cooking up a fix.
- The Android browser doesn’t prompt the user when downloading a file, for example "payload.html", it automatically downloads to /sdcard/download/payload.html
The flaw has been independently verified by Heise.de
, and Google says it will be rolling a fix into Android 2.3 Gingerbread. That could be released as soon as December 6 2010
. Until then, be wary of unexpected downloads or HTML code in emails from users you don't know.
