It’s 2018 and your Macs, iPhones can be pwned by playing evil music: lots of patches

Apple has released security patches for iOS and macOS that include, among other things, Meltdown and Spectre fixes. The new versions should be installed as soon as possible.
Less-hyped, but still serious, are vulnerabilities in the macOS kernel that include an exploitable race condition (CVE-2018-4092), a validation issue (CVE-2018-4093), and memory initialization bug (CVE-2018-4090) that could also allow restricted memory to be read.
Two other kernel flaws, CVE-2018-4097 and CVE-2018-4082, allow an app to run code as the kernel, thus hijacking the whole machine. The first is “a logic issue [..] addressed with improved validation,” discovered by Resecurity Inc, and the second “a memory corruption issue […] addressed through improved input validation” found and reported by Russ Cox of Google.

Other noteworthy bugs include CVE-2018-4094, a bug in both Sierra and High Sierra discovered by five researchers at Yonsei University in Seoul, South Korea. The memory corruption bug allows remote code execution attacks simply by processing a maliciously crafted audio file.

The WebKit browser engine received three fixes for remote code execution flaws (CVE-2018-4088, CVE-2018-4089,CVE-2018-4096) that are also patched in Safari with version 11.0.3.

The QuartzCore component contained a remote code execution flaw (CVE-2018-4085) that can be exploited via web content, while Wi-Fi had a restricted memory access flaw (CVE-2018-4084), and a bug in the operating system’s process sandbox (CVE-2018-4091) could allow programs to get around access restrictions.
Meanwhile, on mobile…

For iOS devices, Apple has served up the 11.2.5 update. It includes a fix for the CVE-2018-4094 audio-file remote-code execution flaw as well as the three kernel memory leak bugs (CVE-2018-4090, CVE-2018-4092, CVE-2018-4093), and the QuartzCore, and WebKit flaws included in the macOS update.

Researcher Abraham “cheesecakeufo” Masri gets credit for CVE-2018-4100, a patched flaw in iOS that allows text messages to crash the iPhone, while Zimperium zLabs’ Rani Idan was credited for CVE-2018-4095 and CVE-2018-4087, a pair of arbitrary code execution flaws in Core Bluetooth.

Masri’s text-message bug, CVE-2018-4100, is also fixed in macOS’s LinkPresentation code to prevent weird text in webpages and messages from stalling desktop apps.

Many of the same iOS flaws are addressed for the Apple Watch in watchOS 4.2.2, and in the AppleTV with tvOS 11.2.5.
