Android’s January 2020 Update Patches 40 Vulnerabilities

Google on Monday published the first Android security bulletin for 2020, with patches for 40 vulnerabilities, including a critical flaw in the Media framework.

The Android Security Bulletin for January 2020 was split into two parts: the first addresses 7 vulnerabilities in Framework, Media framework, and System, while the second includes fixes for 33 security flaws in Kernel, Qualcomm, and Qualcomm closed-source components.

Six of the seven bugs patched with the 2020-01-01 security patch level are rated high severity, and only one is considered critical risk.

“The most severe of these issues is a critical security vulnerability in Media framework that could enable a remote attacker using a specially crafted file to execute arbitrary code within the context of a privileged process,” Google explains.

Tracked as CVE-2020-0002, the vulnerability is only considered critical in Android 8.0, 8.1, and 9 releases, but features a moderate risk rating on Android 10.

Of the three flaws patched in Framework, two are elevation of privilege bugs — one affects Android 8.0, 8.1, 9, and 10, while the other only impacts Android 8.0 — and one is a denial of service issue affecting Android 8.0, 8.1, 9, and 10.

All of the three flaws patched in System are information disclosure bugs that impact Android 8.0, 8.1, 9, and 10.

The second part of this month’s Android security update, namely the 2020-01-05 security patch level, includes fixes for four bugs in Kernel components, eleven flaws in Qualcomm components, and eighteen issues in Qualcomm closed-source components.

The most important of these vulnerabilities is a critical flaw in the Realtek rtlwifi driver, which could result in remote code execution.

Google also published a separate security bulletin detailing vulnerabilities addressed in Pixel devices. A total of 37 fixes were included in the bulletin, with 33 of them being the patches from the 2020-01-05 security patch level and the remaining 4 being moderate severity bugs in Camera.
