Samsung, the world largest mobile manufacturer, by market share is now rolling out the June Security Patch for the Galaxy A5 (2017) and the Galaxy A3 (2017).

The update is in sync with what Samsung usually does nowadays release the security patch for the mid-range prior to other devices.

The June Security Patch from Samsung contains patches for five critical vulnerabilities, among other high- and medium risk vulnerabilities affecting the Android OS, the details of which can be found here. Apart from that, there are patches for three vulnerabilities that were affecting Samsung’s own Android skin. One of these vulnerabilities was regarding the Buffer Overflow in Trustlet, which would have led to memory corruption due to a lack of boundary checking of the buffer in trustlet. Another one of these was related to Information disclosure in the Trustlet, which would expose the Trustlet address information in the log. The last one was related to the Keymaster architecture. As it happens, one of the tlApi was not protected from unspecified trustlet.
