Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 71.0.3578.80

Description The issue is caused by an out-of-bounds operation in the MediaRecorder component of Google Chrome, potentially allowing a remote attacker to exploit heap corruption via a crafted HTML page.
