Security News > 2020 > February > Mind the gap: Google patches holes in Chrome – exploit already out there for one of them after duo spot code fix
Google has updated Chrome for Linux, Mac, and Windows to address three security vulnerabilities - and exploit code for one of them is already public, so get patching.
Interestingly enough, at the time, this public source-code tweak was spotted and studied by Exodus Intelligence researchers István Kurucsai and Vignesh Rao, who hoped to see whether it's still practical to identify security bug fixes among code changes in the Chromium source tree and develop an exploit before the patch sees an official release, a practice known as patch-gapping.
Kurucsai and Rao developed proof-of-concept exploit code for CVE-2020-6418 after spotting the fix buried in the source tree, and before Google could emit an official binary release.
The duo have now shared their exploit code [ZIP] which can be used by white and black hats to target those slow to patch.
In their write-up, Kurucsai and Rao observe that it took three days to analyze the flaw and develop exploit code.
