Google has been forced to issue an emergency update for its Chrome browser after uncovering the most serious type of cyber security flaw. Researcher Salvatore Gulizia discovered the bug within the hugely popular web browser, which has approximately 3.6 billion users worldwide, and reported it to Google. The US tech giant noted that it is something known as a zero-day vulnerability, which has already been exploited by hackers. This type of vulnerability is particularly concerning as it is previously unknown to software developers, meaning there have been zero days to protect against it.It is understood that the security issue could be exploited by tricking someone into visiting an HTML page containing malicious code, which would potentially give attackers control of the affected browser tab. How secure is your chrome browser ?
