Apple this week released its latest desktop operating system iteration, macOS Catalina 10.15, which includes patches for a total of 16 vulnerabilities.
Available as a free software update for all Macs introduced mid-2012 or later, macOS Catalina addresses security flaws in components such as CoreAudio, Crash Reporter, IOGraphics, Kernel, Notes, PDFKit, and WebKit, among others.
The fixed bugs include multiple memory corruption issues, a race condition, a logic issue, an issue with the handling of links in encrypted PDFs and another with the drawing of web page elements, a buffer overflow, a problem with clearing browsing history, and multiple issues in PHP.
These vulnerabilities, Apple says, could lead to arbitrary code execution with kernel privileges, the disclosure of process memory, arbitrary code execution with system privileges, exfiltration of the contents of an encrypted PDF, and the exposure of browsing history.
An issue with SharedFileList could allow malicious applications to access recent documents, a bug in Notes could allow a local user to view locked notes, while a vulnerability in IOGraphics could allow a malicious application to determine kernel memory layout.
Apple also addressed a bug with the “Share Mac Analytics” setting that may not be disabled when a user deselects the switch to share analytics, and also updated PHP to version 7.3.8.
macOS Catalina 10.15 is now available for MacBook (early 2015 and later), MacBook Air (mid-2012 and later), MacBook Pro (mid-2012 and later), Mac mini (late 2012 and later), iMac (late 2012 and later), iMac Pro (all models), and Mac Pro (late 2013 and later).
This week, Apple also released Safari 13.0.2 for macOS Mojave 10.14.6 and macOS High Sierra 10.13.6 (with no published CVEs), iCloud for Windows 10.7, iCloud for Windows 7.14, and iTunes 12.10.1 for Windows.
iCloud for Windows 10.7 and iCloud for Windows 7.14 patch 8 vulnerabilities, including a buffer overflow in UIFoundation (leading to arbitrary code execution), and two logic issues and five memory corruption bugs in WebKit (leading to universal cross-site scripting and arbitrary code execution, respectively).
The same bugs were addressed with the release of iTunes 12.10.1 for Windows, in addition to a memory corruption issue in WebKit that could lead to arbitrary code execution when processing maliciously crafted web content.
