The weaknesses include a loophole that hackers could use to gain access to a victim’s phone.
Most of the problems were fixed after Google informed Samsung, but some remain to be addressed.
An independent expert stated that the bugs significantly compromised the security of Google’s operating system.
According to Dr Steven Murdoch, a security researcher at University College London, tension definitely exists between the handset manufacturers and Google because Google wishes to protect its Android brand, and Android has been quite tarnished when it comes to security. Part of that is due to the extra software added by the handset manufacturers.
Samsung released a statement saying that the remaining three bugs would be fixed via a security update later in November 2015.
The company also added that maintaining the trust of their customers was a top priority.
Details of the bugs were revealed by the Project Zero team of Google, whose purpose is to discover formerly unknown computer security flaws.
It stated that many of the flaws would have been trivial to exploit.
During the course of a week, a sum of 11 issues was found with a serious security effect. Most of these problems were fixed on the device they tested via an over-the-air update within a period of 90 days.
Among the weaknesses was a vulnerability found in Samsung’s email software that could have permitted hackers to send victim’s messages to their own account.
Another permitted hackers to change the settings of Samsung’s photo-viewing app by sending the Samsung Galaxy S6 Edge a particular encoded image.
However, Google stated that the most interesting problem was the existence of a directory traversal bug in a Wi-Fi utility built in to the Samsung Galaxy S6 Edge.
Dr Murdoch explained that if someone supplied malicious data to the software, they could then alter other files on the system and disrupt other functions, specifically security functions. He added that in order to do this, an attacker would also need to persuade their target to install a hostile app, which might seem to have minimal access to the phone’s other functions.
However, by exploiting the weakness, the malware could then increase its privileges.
Dr Murdoch also said that this could only occur as a chain of events, but would in the end permit someone to take over the entire device.
Android attempts to have many layers of protection, so if one level is broken through, there is another one.
This withdrew a few key layers of that protection.
A spokesman added that Samsung encourages their customers to keep their apps and software updated at all times.
