Google has addressed three serious vulnerabilities affecting its Chrome browser that can be exploited to escape the built-in sandbox.
The tech giant released Chrome 77 update in September that addressed two use-after-free vulnerabilities that could lead to sandbox escape.
This month Google released Chrome 78 along with a Chrome 77 update that address three other “high severity” vulnerabilities reported by the same researchers. Chrome 78 addressed a total of 37 vulnerabilities.
The vulnerabilities are a use-after-free issue
An attacker could exploit the vulnerabilities to execute arbitrary code inside the sandbox and potentially escape it, they could be chained with other flaws to compromise the target computer
Google awarded the researchers with $15,000, $20,000 and $15,000, respectively.
