CVE-2019-6234

TITLE

plural Apple Memory corruption vulnerability in products

DESCRIPTION

A memory corruption issue was addressed with improved memory handling. This issue is fixed in iOS 12.1.3, tvOS 12.1.2, Safari 12.0.3, iTunes 12.9.3 for Windows, iCloud for Windows 7.10. 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: * Sandbox avoidance * Arbitrary code execution * Privilege escalation * information leak * Information falsification * Service operation interruption (DoS) * Arbitrary script execution. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the handling of fonts. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. WebKit is prone to the following multiple security vulnerabilities: 1. Multiple remote code-execution vulnerabilities 2. A cross-site scripting vulnerability 3. Multiple memory corruption vulnerabilities Attackers can exploit 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 and perform unauthorized actions; Failed exploit attempts will result in denial-of-service conditions. Apple iOS, etc. are all products of Apple (Apple). Apple iOS is an operating system developed for mobile devices; Safari is a web browser that is the default browser included with Mac OS X and iOS operating systems. tvOS is a smart TV operating system. WebKit is a set of open source web browser engines jointly developed by companies such as KDE, Apple (Apple), and Google (Google), and is currently used by browsers such as Apple Safari and Google Chrome. The following products and versions are affected: Apple iOS prior to 12.1.3; tvOS prior to 12.1.2; Safari prior to 12.0.3; Windows-based iCloud prior to 7.10. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2019-1-22-4 tvOS 12.1.2 tvOS 12.1.2 is now available and addresses the following: AppleKeyStore Available for: Apple TV 4K and Apple TV (4th generation) Impact: A sandboxed process may be able to circumvent sandbox restrictions Description: A memory corruption issue was addressed with improved validation.
