Core Components of Android

When a new version of Android is released, many companies are quick to update their applications to take advantage of the latest features. However, they might not be aware that there are different components within the operating system (OS) that each have more to do with security than they might realize. In this blog post, we'll highlight the most important ones and provide some tips on how you can make your apps as secure as possible.
The major components in this list include:
* Linux Kernel: This is the foundation for Android's computing power. It basically controls what goes on with your device by maintaining security and reliability. Its updates are typically only released once every six months.
* Binder: The binder manages communication between apps through IPC (inter-process communication). Any app downloaded on your phone has access to these functions, so it's important that developers don't abuse them in order to harm other apps or the user's experience.
* ServiceManager: This service manages low-level system services and provides an interface for developers to interact with them when necessary. When you update your app, you need to make sure that it doesn't break anything else in the operating system, which ServiceManager is there to help keep track of and manage.
* TrustZone: TrustZone allows users to run multiple isolated environments in their device at one time without affecting each other too much - this means if one account is compromised then all others will remain safe from malicious software or attacks

CVE-2019-0526 Oracle Outside In-place Update (OIIU) vulnerability - CVE-2018-3015

Bug Description:

The app in the Android framework receives an intent during installation that is used to grant privileges to a component for the app. By exploiting this bug, attackers can gain access to additional permissions on the device that would not normally be available by exploiting other bugs.

CVE-2019-0530 Media framework in Android before version 8.1.0 allows attackers to gain privileges via a crafted app that accesses an intents receiver during installation.

Bug What happens?

CVE-2022-39858 Media framework in Android before version 8.1.0 allows attackers to gain privileges via a crafted app that accesses an intents receiver during installation.
Bug: When the process of installing an application with the intent receiver, it can cause the app to gain super user permissions.
How do we fix this?
Android will update the Media framework to detect and prevent the problem where one out of three apps installed by users can gain privileged access without any interaction from them and just by being installed on their device with default settings.
