Google has made public the details of a medium-level security flaw in Microsoft Edge browser whose patch is still not produced. The vulnerability was first discovered in November 2017, by the search giant’s Project Zero.
According to Engadget, taking advantage of the flaw, hackers could bypass Microsoft Edge’s existing security measures to inject malicious code into a victim’s computer. Google, through its Project Zero, notified Microsoft about a bug in November, giving the company the usual 90-day disclosure deadline.
With the three-month deadline over, the team of security analysts employed by Google tasked with finding zero-day vulnerabilities – Project Zero – went public with the details of the security flaw. The search giant granted a 14-day extension to Microsoft after it said that the problem was complex and it needed more time to fix it.
But, Microsoft even missed the second deadline to produce the patch of the vulnerability. However, given Edge’s small market share, the security issue was unlikely to affect too many people though it is still embarrassing for the company.
Late last year, Microsoft in a blog post had detailed bugs found within Chrome browser. It also criticized Google for its approach in fixing the bugs, while also making the details public. According to Microsoft, Google “made the vulnerability obvious, especially as it came with a regression test”. In addition to this, the stable channel of Chrome was kept vulnerable to the RCE exploit for about a month before releasing the fix to users.
