TITLE

plural Apple Updates to product vulnerabilities

DESCRIPTION

A memory corruption issue was addressed with improved memory handling. This issue is fixed in iOS 13.2 and iPadOS 13.2, macOS Catalina 10.15.1, tvOS 13.2, watchOS 6.1. An application may be able to execute arbitrary code with system privileges. Apple Has released an update for each product.The expected impact depends on each vulnerability, but can be affected as follows: * * information leak * * User impersonation * * Arbitrary code execution * * UI Spoofing * * Insufficient access restrictions * * Service operation interruption (DoS) * * Privilege escalation * * Memory corruption * * Authentication bypass. This vulnerability allows local attackers to disclose sensitive information on affected installations of Apple macOS. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the fseventsd daemon. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute code in the context of the kernel. Apple iOS, etc. are all products of Apple (Apple). Apple iOS is an operating system developed for mobile devices. Apple tvOS is a smart TV operating system. File System Events is one of the file system event reporting components. A security vulnerability exists in the File System Events component of several Apple products. The following products and versions are affected: Apple macOS Catalina prior to 10.15.1; watchOS prior to 6.1; iOS prior to 13.2; iPadOS prior to 13.2; tvOS prior to 13.2. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2019-10-29-2 macOS Catalina 10.15.1, Security Update 2019-001 Mojave, Security Update 2019-006 High Sierra macOS Catalina 10.15.1, Security Update 2019-001 Mojave, Security Update 2019-006 High Sierra are now available and address the following: Accounts Available for: macOS Catalina 10.15 Impact: A remote attacker may be able to leak memory Description: An out-of-bounds read was addressed with improved input validation.
