Multiple memory corruption issues were addressed with improved memory handling. This issue affected versions prior to iOS 12.1.1, tvOS 12.1.1, watchOS 5.1.2, Safari 12.0.2, iTunes 12.9.2 for Windows, iCloud for Windows 7.9. Apple Has released an update for each product.The expected impact depends on each vulnerability, but can be affected as follows: * Privilege escalation * Access restriction avoidance * Arbitrary code execution * Service operation interruption (DoS) * information leak * Incorrect configuration profile usage * UI Spoofing * Address bar impersonation. Apple Safari, etc. are all products of Apple (Apple). Apple Safari is a web browser that is the default browser included with the Mac OS X and iOS operating systems. Apple iOS is an operating system developed for mobile devices. Apple tvOS is a smart TV operating system. WebKit is one of the web browser engine components. A buffer error vulnerability exists in the WebKit component of several Apple products. This vulnerability stems from the incorrect verification of data boundaries when the network system or product performs operations on the memory, resulting in incorrect read and write operations to other associated memory locations. Attackers can exploit this vulnerability to cause buffer overflow or heap overflow, etc. CVE-2018-4438: lokihardt of Google Project Zero Additional recognition Profiles We would like to acknowledge Luke Deshotels, Jordan Beichler, and William Enck of North Carolina State University; Costin CarabaE and RAzvan Deaconescu of University POLITEHNICA of Bucharest for their assistance.
