Subject: [PATCH] Sanitize VPN label to prevent HTML injection
This commit will try to sanitize the content of VpnDialog. This
commit creates a function which will try to sanitize the VPN
label, if the sanitized VPN label is different from the original
one, which means the VPN label might contain HTML tag or the VPN
label violates the words restriction(may contain some wording
which will mislead the user). For this kind of case, show the
package name instead of the VPN label to prevent misleading the
user.
The malicious VPN app might be able to add a large number of line
breaks with HTML in order to hide the system-displayed text from
the user in the connection request dialog. Thus, sanitizing the
content of the dialog is needed.

Subject: [PATCH] Limit the number of supported v1 and v2 signers
The v1 and v2 APK Signature Schemes support multiple signers; this
was intended to allow multiple entities to sign an APK. Previously,
the platform had no limits placed on the number of signers supported
in an APK, but this commit sets a hard limit of 10 supported signers
for these signature schemes to ensure a large number of signers
does not place undue burden on the platform.
Bug: 266580022
Test: Manually verified the platform only allowed an APK with the
maximum number of supported signers.

Subject: [PATCH] DO NOT MERGE Dismiss keyguard when simpin auth'd and...
security method is none. This is mostly to fix the case where we auth
sim pin in the set up wizard and it goes straight to keyguard instead of
the setup wizard activity.
This works with the prevent bypass keyguard flag because the device
should be noe secure in this case.
Fixes: 222446076
Test: turn locked sim on, which opens the sim pin screen. Auth the
screen and observe that keyguard is not shown.

Subject: [PATCH] Truncate ShortcutInfo Id
Creating Conversation with a ShortcutId longer than 65_535 (max unsigned short), we did not save the conversation settings into the notification_policy.xml due to a restriction in FastDataOutput.
This put us to a state where the user changing the importance or turning off the notifications for the given conversation had no effect on notification behavior.
Fixes: 273729476
Test: atest ShortcutManagerTest2
Test: Create a test app which creates a Conversation with a long shortcutId. Go to the Conversation Settings and turn off Notifications. Post a new Notification to this Conversation and see if it is displayed.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix gatt_end_operation buffer overflow
Added boundary check for gatt_end_operation to prevent writing out of
boundary.
Since response of the GATT server is handled in
gatt_client_handle_server_rsp() and gatt_process_read_rsp(), the maximum
lenth that can be passed into the handlers is bounded by
GATT_MAX_MTU_SIZE, which is set to 517, which is greater than
GATT_MAX_ATTR_LEN which is set to 512. The fact that there is no spec
that gaurentees MTU response to be less than or equal to 512 bytes can
cause a buffer overflow when performing memcpy without length check.
Bug: 261068592
Test: No test since not affecting behavior
Tag: #security
Ignore-AOSP-First: security
