Subject: [PATCH] Fix security hole in GateKeeperResponse
|
|
|
|
GateKeeperResponse has inconsistent writeToParcel() and
|
|
createFromParcel() methods, making it possible for a malicious app to
|
|
create a Bundle that changes contents after reserialization. Such
|
|
Bundles can be used to execute Intents with system privileges.
|
|
|
|
We fixed related issues previously for GateKeeperResponse class, but
|
|
one of the case was remaining when payload is byte array of size 0,
|
|
Fixing this case now.
|
|
|
|
Bug: 220303465
|
|
Test: With the POC provided in the bug.
