Though details are scant, Google released a patch for a Google Chrome vulnerability that has been exploited in the wild as a zero day. Background On October 31, Google published a Stable Channel Update for the desktop version of Google Chrome. This release fixes two vulnerabilities, one of which has been exploited in the wild as a zero day.

CVE-2019-13720: Use-After-Free Zero Day in Google Chrome Exploited in the Wild

Use after free in WebAudio in Google Chrome prior to 78.0.3904.87 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

The remote host is affected by the vulnerability described in GLSA-202004-04 (Qt WebEngine: Arbitrary code execution)

    A use-after-free vulnerability has been found in the audio component of       Qt WebEngine.
  Impact :

    A remote attacker could entice a user to open a specially crafted media       file in an application linked against Qt WebEngine, possibly resulting in       execution of arbitrary code with the privileges of the process or a       Denial of Service condition.
  Workaround :

    There is no known workaround at this time.
