Google Patches Critical Android Vulnerabilities With July 2020 Updates

Several critical remote code execution vulnerabilities were addressed in Android this week with the release of the July 2020 set of security patches, including three in the media framework and system components.

Several critical remote code execution vulnerabilities were addressed in Android this week with the release of the July 2020 set of security patches, including three in the media framework and system components.

The most severe of the flaws impacts the system component and could allow an attacker to execute code with high privileges, via a specially crafted file. In fact, Google addressed two critical flaws in the system component, one impacting Android 8.0 and newer releases (CVE-2020-0224), and the other affecting Android 10 only (CVE-2020-0225).

A third vulnerability addressed in system was a high-severity information disclosure issue (CVE-2020-0107) that impacts Android 10 only.

In addition to the patch for a critical remote code execution vulnerability (CVE-2020-9589), media framework received a fix for a high-risk elevation of privilege bug (CVE-2020-0226) affecting Android 10 devices.

All five vulnerabilities are addressed on devices running the 2020-07-01 security patch level. The same patch level fixes two high-severity elevation of privilege flaws in the framework component (impacting Android 8.0 and newer iterations).

The second part of this month’s update, the 2020-07-05 security patch level, brings fixes for two other critical remote code execution bugs (CVE-2019-9501 and CVE-2019-9502), which affect Broadcom firmware.

Two other critical issues were fixed in the Qualcomm WLAN component (CVE-2020-3698 and CVE-2020-3699). The update also addresses two high-severity issues in Qualcomm kernel (CVE-2019-10580) and WLAN (CVE-2020-3700).

Devices that will be updated to the 2020-07-05 security patch level will also receive patches for high-risk flaws in kernel components (three bugs), MediaTek components (three flaws), and Qualcomm closed-source components (five issues). Overall, this month’s patches address 25 vulnerabilities.

In addition to these patches, Pixel devices running the 2020-07-05 security patch level will receive fixes for four moderate-severity bugs affecting Qualcomm components and Qualcomm closed-source components.
