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, 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. This vulnerability allows remote attackers to execute arbitrary code on affected 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 CSSFontFace objects. 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. 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; Windows-based iCloud prior to 10.6 and prior to 7.13; macOS Versions prior to Mojave 10.14.6. ========================================================================== Ubuntu Security Notice USN-4130-1 September 11, 2019 webkit2gtk vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 19.04 - Ubuntu 18.04 LTS Summary: Several security issues were fixed in WebKitGTK+. Software Description: - webkit2gtk: Web content engine library for GTK+ Details: A large number of security issues were discovered in the WebKitGTK+ Web and JavaScript engines.
