This issue is fixed in macOS Catalina 10.15, tvOS 12.3, watchOS 5.2.1, tvOS 13, macOS Catalina 10.15.1, Security Update 2019-001, and Security Update 2019-006, macOS Mojave 10.14.5, Security Update 2019-003 High Sierra, Security Update 2019-003 Sierra, iOS 12.3, iOS 13. Playing a malicious audio file may lead to arbitrary code execution.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceMemory corruption vulnerability in audio file parsing within Apple operating systems. A specially crafted malicious audio file triggers the memory corruption during playback, potentially allowing arbitrary code execution with user privileges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify iOS version on iPhone or iPadGo to Settings > General > About > Version, or run 'sw_vers' in Terminal if you have a computer with iTunes device enumerationAffected if Version is earlier than 12.3, or between 12.3.1 and 12.x before 13.0 (12.3.1 <= version < 13.0)
-
Identify macOS version on MacClick Apple menu > About This Mac, or run 'sw_vers' in TerminalAffected if Version is 10.12.6 through 10.14.5, or 10.14.6 through any version before 10.15
-
Identify tvOS version on Apple TVGo to Settings > General > About > VersionAffected if Version is earlier than 12.3, or between 12.4 and 12.x before 13.0
-
Identify watchOS version on Apple WatchOpen the Watch app on paired iPhone, go to General > About, or check on the watch at Settings > General > AboutAffected if Version is earlier than 5.2.1
You are affected if your device runs any of these Apple operating systems and the OS version falls within the vulnerable ranges listed, and the device supports audio file playback (which is a standard capability on all these platforms).
