Patches for both equally the Chrome desktop and Android browser address substantial-severity flaws with recognised exploits readily available in the wild.
Flaws in Google’s Chrome desktop and Android-based mostly browsers were being patched Monday in an effort to prevent recognized exploits from staying made use of by attackers. Two independent security bulletins issued by Google warned that it is informed of studies that exploits for equally exist in the wild. Google’s Challenge Zero went just one step even further and asserted that both bugs are actively getting exploited.
In its Chrome browser update for Windows, Mac and Linux, Google claimed that model 86..4240.183 fixes 10 vulnerabilities. Tracked as CVE-2020-16009, this bug is the most troubling, rated substantial-severity and is 1 of the two with energetic exploits. The vulnerability is tied to Google’s open up resource JavaScript and WebAssembly engine referred to as V8. In its disclosure, the flaw is described as an “inappropriate implementation in V8”.

“Today Chrome mounted two much more vulnerabilities that were currently being actively exploited in the wild (identified by Venture Zero/Google TAG final week). CVE-2020-16009 is a v8 bug used for distant code execution, CVE-2020-16010 is a Chrome sandbox escape for Android,” he wrote.
Right now Chrome mounted two extra vulnerabilities that ended up currently being actively exploited in the wild (found out by Challenge Zero/Google TAG last 7 days). CVE-2020-16009 is a v8 bug employed for distant code execution, CVE-2020-16010 is a Chrome sandbox escape for Android. https://t.co/IOhFwT0Wx1

And finally there Google reported a “heap buffer overflow in UI on Windows” tracked as (CVE-2020-16011).
This week’s Chrome updates appear on the heels of zero-working day bug claimed and patched previous 7 days by Google effecting Chrome on Windows, Mac and Linux. The flaw (CVE-2020-15999), rated significant-risk, is a vulnerability in Chrome’s FreeType font rendering library.
The most up-to-date vulnerabilities mean that in that just more than 12 months Google has patched a string of major vulnerabilities in its Chrome browser. In addition to the a few most not too long ago noted flaws, the to start with was a critical distant code execution vulnerability patched very last Halloween evening and tracked as CVE-2019-13720, and the next was a type of memory confusion bug tracked as CVE-2020-6418 that was preset in February.
