Google Patches Critical Code Execution Bugs in Android Media Framework

This week, Google released the July 2019 set of patches for the Android operating system, to address a total of 33 vulnerabilities, including 9 rated Critical.

This week, Google released the July 2019 set of patches for the Android operating system, to address a total of 33 vulnerabilities, including 9 rated Critical.

The most severe of these is a critical security vulnerability in the Media framework that allows a remote attacker using a specially crafted file to execute arbitrary code within the context of a privileged process.

The issue was addressed as part of the 2019-07-01 security patch level along with 11 other flaws, Google’s advisory reveals.

Google patched three vulnerabilities in the Android Media framework this month, all of which are remote code execution bugs rated Critical. Two of them (CVE-2019-2106 and CVE-2019-2107) impact all Android releases since 7.0, while the third (CVE-2019-2109) impacts only Android 7.0 to 8.1 iterations.

A fourth Critical vulnerability fixed with the 2019-07-01 security patch level is CVE-2019-2111, a remote code execution bug in System, affecting Android 9.

There were six other flaws addressed in System this month, all of them rated High severity. These include two elevation of privilege bugs (CVE-2019-2112 and CVE-2019-2113) and four information disclosure issues (CVE-2019-2116, CVE-2019-2117, CVE-2019-2118, and CVE-2019-2119).

This security patch level also addresses a High severity information disclosure vulnerability (CVE-2019-2104) in Framework and a High severity remote code execution flaw (CVE-2019-2105) in Library.

The second part of the new set of patches, namely the 2019-07-05 security patch level, fixes 21 vulnerabilities in Qualcomm components (2 Critical and 6 High severity) and Qualcomm closed source components (3 Critical and 10 High severity).

This week, Google also released the July 2019 Pixel Update Bulletin, but it includes only functional patches and no Pixel security fixes.
