Google has recently patched a high severity security bug in the Chrome browser that allowed crooks to send malicious code to your browser and take over your entire system.
The issue, tracked by the CVE-2016-1681 identifier, affects the browser's built-in PDF reader called PDFium.
Google patched the issue with the release of Chrome 51.0.2704.63, released on May 25. In the meantime, Chrome released another wave of security updates at the start of June.
Cisco's Aleksandar Nikolic was the researcher that discovered and reported the issue to Google, who even awarded him $3,000 for his efforts.
According to the researcher's account, the issue was discovered six days earlier, on May 19, and Google's team fixed it right away.
