Wasn’t one of the main goals of junking the Internet Explorer codebase and building a brand new browser “Edge” the hope that there won’t be the monthly batch of patches for remote code execution vulnerabilities?
I haven’t tabulated the advisories but somehow I don’t have the feeling that things have gotten substantially better.
It looks to me like we still aren’t using the right programming environments for such complex pieces of software. There is still way too much basic security tooling the programmers have to do by themselves. Just like you shouldn’t do string operations in pure ANSI C, we need to rise the level of abstractions that all these browser bugs (that lead to RCE) just are not possible any more.
