On Feb 5, 2018 Google released an Android Security Bulletin containing details of security vulnerabilities affecting Android devices. Android security updates normally include two parts: general updates that affect most users and the updates affecting specific partners, such as hardware partners like NVIDIA, Broadcom and Qualcomm. Here we’ve summarized the general security updates on the Android Security bulletin from Security Patch level 2018-02-01.

  • 3 Denial of Service Vulnerabilities: These types of vulnerabilities disable users’ ability to use the phone or access certain services. All vulnerabilities are considered high impact and are found in the Android media framework.
  • 2 Remote Code Execution Vulnerabilities: These types of vulnerabilities allow attackers to execute arbitrary code on user devices. All of them are considered critical severity and are found in the Android media framework.
  • 2 Privilege Escalation Vulnerabilities: These types of vulnerabilities allow unprivileged processes, such as from third-party apps, to escalate privileges to the system level, bypassing the sandbox restrictions. One is rated as high impact and is found in media framework, while another is rated as moderate impact and is found in the system libraries.
  • 1 Information Disclosure Vulnerability: This vulnerability allows malicious apps to access user data. It is rated as high impact and is found in the Android media framework.

Appthority urges users to update their Android devices to the latest OS version which includes these security updates. We also recommend enterprise IT admins set strong policies against keeping outdated OS versions on their employees’ mobile devices.
