The Brief

Google patched a high-severity use-after-free bug in Chrome's XML component.
The flaw was reported anonymously on November 6 and is already being exploited in attacks.
SecurityWeek describes it as the eighth Chrome zero-day this year.

An actively exploited browser flaw puts any unpatched Chrome installation at risk, so developers and their machines should update promptly.
