No piece of software is perfect, and sometimes vulnerabilities can go undiscovered for a long time. For instance, a WinRAR flaw was out in the open for almost two decades. Google’s latest Chrome bug isn’t that old, but it’s much more dangerous. Google has issued a patch for the vulnerability, but this is a “zero-day” flaw, meaning there are already online troublemakers using the vulnerability to attack Chrome. If you haven’t let Chrome update recently, take the time to do it now.
