Microsofts Offensive Security Research (OSR) team disclosed a remote code execution vulnerability in the Chrome web browser that was discovered by its experts. The flaw, tracked as CVE-2017-5121, was addressed by Google last month with the release of Chrome 61. Microsoft criticized the way Google releases patches for Chrome through the open-source browser project Chromium. The source code changes that address the flaw are often available on GitHub before the actual patch is released to customers allowing threat actors to develop their own exploit codes.”]
