From 9037e43fa8dfebaceea752e137a754593d752eb7 Mon Sep 17 00:00:00 2001 From: Hugh Chen Date: Thu, 17 Dec 2020 11:29:31 +0800 Subject: [PATCH] RESTRICT AUTOMERGE Fix phishing attacks over Bluetooth due to unclear warning message Before this CL, there is a possible phishing attack allowing a malicious BT device to acquire permissions based on insufficient information presented to the user in the consent dialog. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation. This CL add more prompts presented for users to avoid phishing attacks. Merge Conflict Notes: There were a number of entries in strings.xml that did not exist on this branch. However, as the CL only adds new entries rather than modifying old ones this should not cause a problem. There were no merge conflicts in the java files. Bug: 167403112 Test: send intent to test right prompts message is pop up. make -j42 RunSettingsRoboTests Change-Id: Idc6ef558b692115bb82ea58cf223f5919b618633 --- res/values/strings.xml | 13 +++++++++++++ .../bluetooth/BluetoothPermissionActivity.java | 12 ++++++------ .../bluetooth/BluetoothPermissionRequest.java | 9 +++++---- 3 files changed, 24 insertions(+), 10 deletions(-) diff --git a/res/values/strings.xml b/res/values/strings.xml index 8265475a987..d65f31cdda0 100644 --- a/res/values/strings.xml +++ b/res/values/strings.xml @@ -9052,4 +9052,17 @@ This feature is not available on this device + + + Untrusted device wants to access your messages.
