The vulnerability affects all versions of Android including Froyo or Android 2.2 and popular smartphones including HTC Desire that run Froyo. Facebook has since fixed the vulnerability affecting any form of Android using its existing vulnerability scanner.
The vulnerability, according to security firm Checkbridge, affects Facebook’s own code and violates the code of the Android Open Source Project.
