Technologies: Google Chrome. Vendors: Google.

Executive brief

A security vulnerability exists in the Google Chrome web browser's Cast component, which is used for streaming content to other devices. An attacker could exploit this flaw by tricking a user into visiting a specially crafted website, potentially allowing the attacker to run unauthorized code on the user's computer. While the attack is limited by the browser's security sandbox, it still represents a significant risk to system integrity and user data.

Technical details

A use-after-free (UAF) vulnerability exists in the Cast component of Google Chrome. The flaw is triggered when the browser incorrectly manages memory during the lifecycle of Cast-related objects, allowing a remote attacker to achieve arbitrary code execution within the renderer process sandbox.
