Details: The software does not properly validate an application's certificate chain. An application can supply a specially crafted application identity certificate to impersonate a privileged application and gain access to vendor-specific device administration extensions. The vulnerability resides in the createChain() and findCert() functions of the Android JarUtils class. [securitytracker-1030654]

Fixed versions: there is no single, specific “fixed” version of Android. In fact, multiple vendors are maintaining the same prior version number, and only patching the functionality. We have confirmed “fixed” versions existing within the ranges of 4.1, 4.2, 4.3, and 4.4 [bluebox-fakeid]
