Apple has released security fixes for several vulnerabilities in Mac and iOS software. Affected services include iOS, Safari, iCloud, iTunes for Windows, tvOS, and macOS Mojave, High Sierra, and Sierra. All December patches can be installed via Software Update.
MacOS updates will arrive in Mojave 10.14.2, High Sierra security update 2018-003, and Sierra security 2018-006. They address 13 CVEs, including two for WindowServer (CVE-2018-4449 and CVE-2018-4450), one in Disk Images (CVE-2018-4465), one in Carbon Core (CVE-2018-4463), one in Intel Graphics Driver (CVE-2018-4434), and one in IOHIDFamily (CVE-2018-4427).
There are five CVEs for Kernel addressing a denial-of-service vulnerability (CVE-2018-4460), kernel memory disclosure (CVE-2018-4431), and three that would let an attacker or application elevate privileges and execute code (CVE-2018-4435, CVE-2018-4461, CVE-2018-4447).
The iOS 12.1.1 update comes with all patches for Airport, Disk Images, Kernel, Safari, and WebKit. It also fixes a vulnerability in FaceTime (CVE-2018-4430), which could let an attacker view contacts from the lock screen, and a File Provider bug (CVE-2018-4446), which could share data on the device's other applications. Other iOS-specific CVEs affect LinkPresentation (CVE-2018-4429), which could enable user interface spoofing, and Profiles (CVE-2018-4436).
Safari version 12.0.2 brings six WebKit patches addressing issues that could lead to arbitrary code execution. It also patches vulnerabilities that could lead to address bar spoofing (CVE-2018-4440) or user interface spoofing (CVE-2018-4439), or prevent users from deleting their browser histories (CVE-2018-4445).
