Use after free in task scheduling in Google Chrome prior to 81.0.4044.129 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page.

The remote CentOS Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:1981 advisory.

  - Use after free in storage in Google Chrome prior to 81.0.4044.129 allowed a remote attacker who had     compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page.
