On July 5, 2017 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 2017-07-01.
- 17 Remote Code Execution Vulnerabilities: These types of vulnerabilities allow attackers to execute arbitrary codes on user devices. Ten of the discovered vulnerabilities are considered critical, six are considered high severity, and one is considered moderate severity. The vulnerabilities are found in the Android media framework, Android runtime, Android framework, system libraries (such as libnl and libskia), and the System UI.
- 15 Denial of Service Vulnerabilities: These types of vulnerabilities disable users’ ability to use the phone or access certain services. All of them are considered high impact. The vulnerabilities are found in system libraries and the Android media framework.
- 7 Privilege Escalation Vulnerability: This type of vulnerability allows unprivileged processes, such as from third-party apps, to escalate privileges to the system-level bypassing the sandbox restrictions. Six of them are rated as high impact, while one is rated as medium impact. One of this type of vulnerability is found in Android framework, Android media framework and System UI.
- 4 Information Disclosure Vulnerabilities: These vulnerabilities allow malicious apps to access user data. One is rated as high impact and the rest are rated as medium impact. The vulnerabilities are found in Android framework and Android media framework.
This security update also addresses the “Broadpwn” vulnerability, which allows an attacker to remotely exploit HTC, LG, Nexus and Samsung devices. The attack also works on iOS devices, although the affected models are currently unknown.
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 We also recommend enterprise IT admins set strong policies against keeping outdated OS versions on their employees’ mobile devices.
