Apple Patches Vulnerabilities Across All Platforms

Apple this week released security patches for all four of its operating systems to resolve tens of security bugs in each of them.

The tech giant addressed 37 vulnerabilities with the release of macOS Sierra 10.12.6 (and Security Update 2017-003 El Capitan and Security Update 2017-003 Yosemite). The vast majority of the issues could result in arbitrary code execution. Impacted components include audio, Bluetooth, contacts, Intel graphics driver, kernel, libarchive, and libxml2, Apple reveals.

The release of iOS 10.3.3 adressed 47 vulnerabilities, many allowing for arbitrary code execution and some for unexpected application termination or information disclosure. WebKit was the most affected component, with over 20 bugs squashed in it. Kernel, Safari, messages, contacts, libarchive, and libxml2 were also among the affected components.

Tracked as CVE-2017-9417 and affecting Broadcom's BCM4354, 4358, and 4359 chips, one of the vulnerabilities could allow an attacker within range to execute arbitrary code on the Wi-Fi chip. Because said chips are used in various smartphones, including devices from HTC, LG, and Samsung, Google too addressed the issue with its latest Android patches.

Apple addressed 16 security flaws with the release of watchOS 3.2.3, including CVE-2017-9417. Kernel was affected the most, with 9 bugs resolved in it. Contacts, IOUSBFamily, libarchive, libxml2, libxpc, messages, and Wi-Fi were also impacted. These vulnerabilities could result in arbitrary code execution, unexpected application termination, information disclosure, or an app’s ability to read restricted memory.

Apple's tvOS 10.2.2 resolves 38 bugs, most of which affect WebKit and Kernel (they were addressed in iOS and watchOS as well). Most of these issues could lead to arbitrary code execution, in some cases with elevated privileges (kernel or system), Apple notes in its advisory.

Apple also released Safari 10.1.2 this week, addressing a bug in Safari Printing and 24 issues in WebKit or related to it. iTunes 12.6.2 for Windows patches 23 security issues (one in iTunes, another in libxml2, and 21 in WebKit), while iCloud for Windows 6.2.2 resolves 22 vulnerabilities (one in libxml2 and 21 in WebKit).
