Microsoft tears into Chrome security as patching feud continues
Google Vulnerability research
The ding-dong between Microsoft and Google vulnerability researchers is not yet an inter-generational conflict but it’s showing signs of turning into one.
Identified as CVE-2017-5121, the flaw in the just-in-time compiler was patched by Google in September (Chrome 61.0.3163.100), which we now know was reported to the company by Microsoft because, the company’s blog reveals, its team were paid a $7,500 (£5,700) bug bounty by Google.
Normally, that would be that, except that Microsoft’s dissection swiftly turns into a launchpad for a broader critique of weaknesses in Chrome’s design. For example:
Chrome’s relative lack of RCE mitigation means the path from memory corruption bug to exploit can be a short one.
