Android May 2019 Patches Fix Critical Remote Code Execution Vulnerabilities

The May 2019 set of security patches released for the Android operating system address 8 Critical vulnerabilities, including 4 remote code execution flaws. 

The most severe of the resolved issues is a critical bug in Media framework that could be exploited remotely using a specially crafted file to execute arbitrary code within the context of a privileged process. 

Tracked as CVE-2019-2044, the vulnerability impacts Android 7.0, 7.1.1, 7.1.2, 8.0, 8.1, and 9 and was addressed on all devices running the Android 2019-05-01 security patch level. 

Other Critical vulnerabilities addressed in this patch level include 3 remote code execution flaws in System (CVE-2019-2045, CVE-2019-2046, and CVE-2019-2047). The issues impact Android 7.0, 7.1.1, 7.1.2, 8.0, 8.1, and 9. 

Five other vulnerabilities were addressed in System this month, including two elevation of privilege (CVE-2019-2049 and CVE-2019-2050) and three information disclosure (CVE-2019-2051, CVE-2019-2052, and CVE-2019-2053) flaws. All five are rated High severity.

The Android 2019-05-01 security patch level also fixes a Moderate risk elevation of privilege bug in Framework (CVE-2019-2043), Google explains in an advisory.

The second part of this month’s set of Android patches addresses issues in Kernel components, NVIDIA components, Broadcom components, Qualcomm components, and Qualcomm closed-source components. 

Addressed on all devices running the Android 2019-05-05 security patch level, these flaws include a Moderate severity elevation of privilege bug in Kernel components, a High risk severity elevation of privilege issue in NVIDIA components, and a High risk remote code execution vulnerability in Broadcom components.

Two flaws addressed in Qualcomm components were rated High severity, while the 15 issues resolved in Qualcomm closed-source components included 4 Critical severity and 11 High risk bugs. 

The same as in the past several months, the Pixel Update Bulletin for May 2019 contains no security patches. No functional patches were released for these devices either.

However, Pixel devices will receive an update that will deliver fixes for the issues in the May 2019 Android Security Bulletin.
