PNG images: It is known that Google is circulating several security updates for Android. The most recent is February 2019 update with corrections for about 42 errors. Due to the size of the updates, many of you may have missed some in the past. There is an important reason why you should not miss these updates.
Among 42 errors, fix a critical vulnerability that has been able to "exterminate" your device. Let's look at the problem more carefully.
Of course, nothing is impeccable. Manufacturers often release updates to touch perfection with their devices. The same goes for the Google gossip, of course.
The latest update corrected a deadly issue that affected several Android users. In fact, the error could allow one hacker to sow a malware simply by sending a PNG image. As soon as users open the image, malware is turned on and it destroys everything.
The negative of the case is that, so far, only the pixel devices have received the update and all other Android users will have to wait for the manufacturer of our device to act accordingly.
The reasonable question is: How will I stay safe when I am an Android user without Pixel?
- Do not open pictures from SMS or from unreliable emails.
- Make sure to control the extension of each image and avoid PNG files. Opening a PNG file can result in automatic download of a malware.
Vulnerability has been identified in three forms (CVE-2019-1986, CVE-2019-1987, and CVE-2019-1988). The positive thing is that the problem only affects the devices that run Android 7.0 and newer versions.
Google, for its part, claims that there are so far no reports of vulnerability. However, the security patch needs to be installed by everyone.
