Google Android 4.3 KeyStore Service Local Stack-based Buffer Overflow

This script is Copyright (C) 2014-2017 Tenable Network Security, Inc.


Synopsis :

The version of Google Android running on the mobile device is affected
by a local stack-based buffer overflow in the KeyStore service.

Description :

The mobile device is running Google Android version 4.3. It is,
therefore, affected by a local stack-based buffer overflow in the
KeyStore Service. The issue is due to user-supplied input to the
'encode_key' function in the KeyStore service not being properly
validated. This allows a local attacker to execute arbitrary code in
the context of the application and to disclose sensitive information.
