Today’s Daily Byte covers two subjects, both involving Google security research.
The biggest story is the CloudBleed vulnerability. Tavis Ormandy, a well-known Google security researcher, found that websites using the CloudFlare service were sending corrupt HTTPS replies. Turns out, the replies contained information from the memory of the servers hosting these sites, which could include things like passwords and digital keys. CloudFlare has since fixed a the bug that lead to this issue.
I also cover a new zero day Internet Explorer (IE) and Edge vulnerability that Google’s Project Zero released without a Microsoft patch. Similar to an issue from last week, Google disclosed this vulnerability publicly since Microsoft didn’t make their mandatory 90 day disclosure deadline. This disclosure puts Microsoft browser users at risk until a patch is available.
Watch the video below for more details on both these issues, and whether or not you really need to worry about this CloudBleed issue.
