TITLE

plural Apple Updates to product vulnerabilities

DESCRIPTION

Multiple memory corruption issues were addressed with improved memory handling. This issue is fixed in iOS 12.4, macOS Mojave 10.14.6, tvOS 12.4, watchOS 5.3, Safari 12.1.2, iTunes for Windows 12.9.6, iCloud for Windows 7.13, iCloud for Windows 10.6. Processing maliciously crafted web content may lead to arbitrary code execution. Apple Has released an update for each product.The expected impact depends on each vulnerability, but can be affected as follows: * Arbitrary code execution * Insufficient access restrictions * information leak * Service operation interruption (DoS) * Information falsification * Privilege escalation * Sandbox avoidance. WebKit is prone to a cross-site scripting vulnerability and multiple memory-corruption vulnerabilities. An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site or execute arbitrary code in the context of the affected system. This may allow the attacker to steal cookie-based authentication credentials and launch other attacks. Failed exploit attempts will likely cause a denial-of-service condition. 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 memory corruption vulnerability exists in the WebKit component of several Apple products. The following products and versions are affected: Apple iOS prior to 12.4; Windows-based iTunes prior to 12.9.6; tvOS prior to 12.4; Safari prior to 12.1.2; macOS Mojave prior to 10.14.6; watchOS prior to 5.3.
