Doc Text:
A flaw was found in chromium-browser. A remote attacker could exploit a memory corruption issue in the Extensions component by tricking a user into visiting a specially crafted HTML page, potentially allowing arbitrary code execution within the browser's sandbox. While execution is confined to the sandbox—an isolated security environment—this flaw compromises the affected browser process.
