Description Preview
A vulnerability exists in the Android Verified Boot (AVB) system, specifically in the avb_vbmeta_image_verify function of avb_vbmeta_image.c. The function fails to properly validate bounds before performing read operations, which could lead to an out-of-bounds read. This vulnerability could allow a local attacker with system execution privileges to access sensitive information. No user interaction is required for exploitation.
Overview
CVE-2020-0151 is a buffer overflow vulnerability (CWE-125: Out-of-bounds Read) affecting Android 10 devices. The issue exists in the Android Verified Boot (AVB) component, which is responsible for ensuring the integrity of the boot process. The vulnerability specifically occurs in the avb_vbmeta_image_verify function within avb_vbmeta_image.c, where a missing bounds check allows potential out-of-bounds memory reads. This could expose sensitive information to an attacker who has already gained system execution privileges on the device. The vulnerability is particularly concerning for the security of Android's boot verification process, which is designed to prevent unauthorized modifications to the system.
Remediation
- Update affected Android devices to the security patch level from June 2020 or later.
- Apply the security updates provided in the Android Security Bulletin for Pixel devices dated June 1, 2020.
- If you are an OEM or system developer using AVB components, ensure you've incorporated the patched versions of the affected code.
- End users should ensure their devices are set to receive and install security updates automatically.
- Organizations with managed Android devices should prioritize the deployment of this security update, especially for devices containing sensitive information.
