Description

This security bulletin contains information about 14 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2020-0021)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists within the Framework functionality of Android due to a missing package dependency test in "removeUnusedPackagesLPw" of "PackageManagerService.java". A remote attacker can cause a denial of service condition on the target system.


2) Out-of-bounds read (CVE-ID: CVE-2020-0020)

The vulnerability allows a local attacker to gain access to potentially sensitive information.

The vulnerability exists within the Framework functionality of Android due to a boundary condition in "getAttributeRange" of "ExifInterface.java" when the vulnerable software fails to redact location information from media files. A local attacker can trigger out-of-bounds read error and read contents of memory on the system.


3) Information disclosure (CVE-ID: CVE-2020-0018)

The vulnerability allows a local attacker to gain access to potentially sensitive information.

The vulnerability exists within the Framework functionality of Android due to an error in "MotionEntry::appendDescription" of "InputDispatcher.cpp". A local attacker can gain unauthorized access to sensitive information on the system.


4) Information disclosure (CVE-ID: CVE-2020-0017)

The vulnerability allows a local attacker to gain access to potentially sensitive information.

The vulnerability exists within the Framework functionality of Android due to a possibility for the primary users dictionary to be visible to and modifiable by secondary users in multiple places. A local attacker can gain unauthorized access to sensitive information on the system.


5) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-2200)

The vulnerability allows a local attacker to escalate privileges on the system.

The vulnerability exists due to a permission bypass in "updatePermissions" of "PermissionManagerService.java". A local attacker can use a malicious app to obtain a custom permission from another app and gain elevated privileges on the target system.


6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-0015)

The vulnerability allows a local attacker to escalate privileges on the system.

The vulnerability exists within the Framework functionality of Android due to a possible way to overlay the Certificate Installation dialog by a malicious application in "onCreate" of "CertInstaller.java". A local attacker can gain elevated privileges on the target system.


7) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-0014)

The vulnerability allows a local attacker to escalate privileges on the system.

The vulnerability exists within the Framework functionality of Android due to possibility for a malicious application to construct a TYPE_TOAST window manually and make that window clickable. A local attacker can gain elevated privileges on the target system.


8) Information disclosure (CVE-ID: CVE-2020-0028)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists within the System functionality of Android due to a possible bypass of private DNS settings in "notifyNetworkTested" and related functions of "NetworkMonitor.java". A remote attacker can gain unauthorized access to sensitive information on the system.


9) Out-of-bounds write (CVE-ID: CVE-2020-0027)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists within the System functionality of Android due to an unexpected switch fallthrough in "HidRawSensor::batch" of "HidRawSensor.cpp". A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.


10) Use-after-free (CVE-ID: CVE-2020-0026)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists within the System functionality of Android due to a use-after-free error in "Parcel::continueWrite" of "Parcel.cpp". A remote attacker can gain elevated privileges on the target system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


11) Information disclosure (CVE-ID: CVE-2020-0023)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists within the System functionality of Android due to a missing permission check in "setPhonebookAccessPermission" of "AdapterService.java". A remote attacker can gain unauthorized access to sensitive information if a malicious app enables contacts over Bluetooth.


12) Out-of-bounds write (CVE-ID: CVE-2020-0022)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists within the System functionality of Android due to a boundary error when processing untrusted input in "reassemble_and_dispatch" of "packet_fragmenter.cc". A remote attacker can trigger out-of-bounds write and execute arbitrary code over Bluetooth on the target system.


13) Out-of-bounds write (CVE-ID: CVE-2020-0005)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists within the System functionality of Android due to a boundary error when processing untrusted input in "btm_read_remote_ext_features_complete" of "btm_acl.cc". A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.


14) Race condition (CVE-ID: CVE-2020-0030)

The vulnerability allows a local attacker to escalate privileges on the system.

The vulnerability exists within the "Binder driver" component of Android due to a race condition in "binder_thread_release" of "binder.c". A local attacker can use a specially crafted file to exploit the race, trigger a use-after-free error and execute arbitrary code with elevated privileges on the target system.
