A flaw was found in chromium-browser. A remote attacker could exploit an out-of-bounds read vulnerability in the Tint component by enticing a user to visit a specially crafted HTML page. This could potentially allow the attacker to read sensitive memory within the browser's sandbox, a security mechanism that isolates processes to limit their access to system resources.
