Subject: [PATCH] RESTRICT AUTOMERGE: Drop invalid data.
|
||||
|
||||
Drop invalid data when writing or reading from XML. PersistableBundle
|
||||
does lazy unparcelling, so checking the values during unparcelling would
|
||||
remove the benefit of the lazy unparcelling. Checking the validity when
|
||||
writing to or reading from XML seems like the best alternative.
|
||||
|
||||
Bug: 246542285
|
||||
Bug: 247513680
|
||||
Test: install test app with invalid job config, start app to schedule job, then check logcat and jobscheduler persisted file

Subject: [PATCH] Fix UAF in ~CallbackEnv
|
||||
|
||||
com_android_bluetooth_btservice_AdapterService does not null its local
|
||||
JNI environment variable after detaching the thread (which frees the
|
||||
environment context), allowing UAF under certain conditions.
|
||||
|
||||
Null the variable in this case.
|
||||
|
||||
Testing here was done through a custom unit test; see patchsets 4-6 for
|
||||
contents. However, unit testing of the JNI layer is problematic in
|
||||
production, so that part of the patch is omitted for final merge.

|

Because Telecom grants the INTERACT_ACROSS_USERS permission, an exploit
|

is possible where the user can upload an image icon (belonging to
|

another user) via registering a phone account. This CL provides a

lightweight solution for parsing the image URI to detect profile

exploitation.

Subject: [PATCH] Fix timing attack in BTM_BleVerifySignature
|
||||
|
||||
BTM_BleVerifySignature uses a stock memcmp, allowing signature contents
|
||||
to be deduced through a side-channel attack.
|
||||
|
||||
Change to CRYPTO_memcmp, which is hardened against this attack, to
|
||||
eliminate this attack.

Subject: [PATCH] Fix Heap-use-after-free in MDnsSdListener::Monitor::run
|
||||
|
||||
Use thread join to avoid thread exiting after instance
|
||||
recycled.
|
||||
|
||||
Prior to implementing this patch, fuzzing would lead to a segmentation fault after approximately 500 rounds. With the addition of the patch, the fuzzing process can now be repeated for over 30,000 rounds.
|
||||
|
||||
Test: m, fuzzing
