The latest security maintenance release brings several bug fixes for Android OS from Google. It also applies fixes for multiple vulnerabilities that were discovered in Samsung's custom software. You can expect firmware updates with this patch to start rolling out in the coming days.
Samsung monthly updates will start sending out the June 2019 patch
The June 2019 security patch brings fixes for eight critical vulnerabilities in Android OS in addition to over a dozen high-risk vulnerabilities. One vulnerability flagged as moderate-risk has been patched as well. The most severe critical security vulnerability could have allowed a remote attacker to use a special file to run arbitrary code on a device in the context of a privileged process. Google has had no reports of active customer exploitation of these issues.
11 Samsung Vulnerabilities and Exposures (SVE) items have been patched with the June 2019 release as well. They include the use of insecure HTTP link in the Galaxy Store. Select apps in the store used HTTP to check update availability which may have allowed remote attackers to launch a Man-in-the-Middle attack to download infected apps. This patch changes the app update checking URL to HTTPS.
Many of the company's recent devices will soon receive the latest release as part of the Samsung monthly updates program. We'll be sure to let you know as soon as the firmware updates start rolling out.
