Google Fixes Critical Android Vulnerabilities
5.7.18 securityweek  Vulnerebility

Google this week released its July 18 set of Android patches to address tens of vulnerabilities in the mobile operating system, including several rated as Critical.

The Internet giant addressed 11 vulnerabilities as part of the 18-07-01 security patch level, including three rated Critical and 8 High risk bugs. The issues impact framework, media framework, and system.

All three Critical severity bugs are remote code execution flaws, one for each of the impacted components. The remaining vulnerabilities include information disclosure bugs, elevation of privilege issues, and denial of service flaws.

“The most severe vulnerability in this section could enable a remote attacker using a specially crafted file to execute arbitrary code within the context of a privileged process,” Google notes in an advisory.

Affected operating system versions include Android 6.0, 6.0.1, 7.0, 7.1.1, 7.1.2, 8.0, and 8.1.

A total of 32 flaws were addressed as part of the 18-07-05 security patch level, 8 rated Critical severity and 24 considered High risk.

These issues impact Kernel, Qualcomm, and Qualcomm closed-source components such as IPV6 stack, futex, USB driver, WLAN, nsfs, OpenGL ES driver, and ADSPRPC heap manager.

Of the resolved vulnerabilities, 22 were impacting Qualcomm closed-source components. These include 7 Critical issues and 15 High risk flaws.

6 vulnerabilities were addressed in Qualcomm components, including a Critical remote code execution flaw, one High severity remote code execution bug, two High risk information disclosure issues, and two elevation of privilege vulnerabilities.

All of the 4 flaws addressed in Kernel components were elevation of privilege bugs.

This month, Google also addressed 26 Medium severity issues impacting Pixel and Nexus devices. Affected components include framework, media framework, system, Kernel components, and Qualcomm components.

Most of the addressed issues were elevation of privilege bugs, but remote code execution and information disclosure security vulnerabilities were also addressed.

Additionally, the Internet giant released a functional update for the Pixel and Nexus devices, to “improve consistency of Wi-Fi connections with certain routers,” the advisory reads.

Last month, Google addressed a dozen Critical flaws in Android, along with tens of High risk issues. The company also resolved over 60 vulnerabilities affecting Pixel and Nexus devices, most of which were rated Medium severity.
