Apple Security Updates December 2018 released a set of security updates for its products this month. There are ten products which received the updates including Apple’s new brain child, MacOS Mojave which newly launched in September. This update addresses a set of 26 vulnerabilities which a vulnerability scanning tool found. And, the products listed under this update are macOS Mojave 10.14.2, Security Update 2018-003 High Sierra, Security Update 2018-006 Sierra, iCloud, Safari, iTunes, tvOS, iOS, watchOS 5.1.2, Shortcuts 2.1.2 for iOS.

A good 13 CVEs out of 26 could lead to Arbitrary Code Execution. Three interesting CVEs: CVE-2018-4446, CVE-2018-4303 and CVE-2018-4435, aid malicious applications running on the system to elevate privileges and gather information about other applications running on the system. Auto patching can patch these critical vulnerabilities quickly.

In the limelight: Mojave

The second set of updates for Mojave are considered important as they are said to improve the performance, compatibility, stability and the security. Eleven vulnerabilities reported for MacOS. Five CVEs: CVE-2018-4303, CVE-2018-4463, CVE-2018-4434, CVE-2018-4460, and CVE-2018-4461 are unique to Mojave, out of which three are rated Critical for Arbitrary Code Execution and restricted kernel memory access. Also, these updates are believed to have addressed the issues with wifi and battery drain that reported by customers last month.

Critical Vulnerabilities

Six CVEs are rated critical and have memory corruption issues. The first four CVEs listed lead to Arbitrary Code Execution with Kernel Privileges,

  1. CVE-2018-4427 lists a flaw in the IOHIDFamily of macOS Sierra 10.12.6, macOS High Sierra 10.13.6 which leads to privilege escalation and a flaw in the Disk Images of  tvOS(Apple TV 4K and Apple TV (4th generation)) and watchOS(Apple Watch Series 1 and later).
