VAR-202104-0617
Vulnerability from variot - Updated: 2024-11-23 21:02An out-of-bounds read was addressed with improved input validation. This issue is fixed in iOS 14.4 and iPadOS 14.4. A remote attacker may be able to cause arbitrary code execution. iOS and iPadOS Exists in an out-of-bounds read vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) May be in a state. Apple Bluetooth is a component used by Apple in the United States to support Bluetooth in Apple mobile devices. A resource management error vulnerability exists in Apple Bluetooth due to an out-of-bounds read of input. The following products and models are affected: Apple iOS 14.4 and iPadOS 14.4. Apple iOS and iPadOS could allow a remote malicious user to execute arbitrary code on the system, caused by an out-of-bounds read in the Bluetooth component. By persuading a victim to visit a specially crafted Web site, an attacker could exploit this vulnerability to execute arbitrary code on the system with elevated privileges
