Using an Android device?
Beware! You have to remain more caution while opening an image file on your smartphone—downloaded anywhere from the Internet or received through messaging or email apps.
Yes, just viewing an innocuous-looking image could hack your Android smartphone—thanks to three newly-discovered critical vulnerabilities that affect millions of devices running recent versions of Google’s mobile operating system, ranging from Android 7.0 Nougat to its current Android 9.0 Pie.
The vulnerabilities, identified as CVE-2019-1986, CVE-2019-1987, and CVE-2019-1988, have been patched in Android Open Source Project (AOSP) by Google as part of its February Android Security Updates.
However, since not every handset manufacturer rolls out security patches every month, it’s difficult to determine if your Android device will get these security patches anytime sooner.
Although Google engineers have not yet revealed any technical details explaining the vulnerabilities, the updates mention fixing “heap buffer overflow flaw,” “errors in SkPngCodec,” and bugs in some components that render PNG images.
According to the advisory, one of the three vulnerabilities, which Google considered to be the most severe one, could allow a maliciously crafted Portable Network Graphics (.PNG) image file to execute arbitrary code on the vulnerable Android devices.
