Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A memory consumption issue was addressed with improved memory handling. This issue is fixed in tvOS 16, iOS 16, macOS Ventura 13, watchOS 9. Processing a maliciously crafted image 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 · moderate confidence

A vulnerability in Apple's image processing frameworks allows arbitrary code execution when processing maliciously crafted images. The issue stems from improper memory handling during image parsing, likely a buffer overflow or similar memory corruption flaw that can be triggered by specially crafted image files.

MitigationUpdate affected devices to iOS 16, tvOS 16, watchOS 9, or macOS Ventura 13 or later. For applications that process untrusted images, implement strict input validation and consider sandboxing image processing operations.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the Apple device type and operating system
    Determine whether the system is an iPhone, iPad, Mac, Apple TV, or Apple Watch, and note which operating system it runs (iOS, macOS, tvOS, or watchOS)
    Affected if The device runs an Apple operating system that matches the affected product list
  2. Check the installed iOS version
    On iPhone or iPad, go to Settings > General > About, or use the 'sw_vers' command in terminal, or check via Apple Configurator or MDM tools
    Affected if iOS version is lower than 16.0
  3. Check the installed macOS version
    Click the Apple menu > About This Mac, or run 'sw_vers' in Terminal, or check via System Preferences > General
    Affected if macOS version is lower than 13.0 (Ventura)
  4. Check the installed tvOS version
    Go to Settings > General > About on Apple TV, or check via Xcode or MDM tools
    Affected if tvOS version is lower than 16.0
  5. Check the installed watchOS version
    Open the Watch app on paired iPhone, go to General > About, or check via Apple Configurator
    Affected if watchOS version is lower than 9.0

The environment is affected if any Apple device runs an operating system version below the patched releases (iOS 16, macOS 13, tvOS 16, or watchOS 9) and uses image processing capabilities to handle untrusted image files.

Upgrade available Upgrade to 9.0 / 13.0 / 16.0 or later
Fixed in 9.013.016.0
Interim mitigation

Update affected devices to iOS 16, tvOS 16, watchOS 9, or macOS Ventura 13 or later. For applications that process untrusted images, implement strict input validation and consider sandboxing image processing operations.

Recommended fix High confidence

iOS 16.0+, macOS Ventura 13.0+, tvOS 16.0+, watchOS 9.0+

  1. For iPhone/iPad: Go to Settings > General > Software Update and upgrade to iOS 16.0 or later
  2. For Mac: Go to System Preferences > Software Update and upgrade to macOS Ventura 13.0 or later
  3. For Apple TV: Go to Settings > System > Software Updates and upgrade to tvOS 16.0 or later
  4. For Apple Watch: On your iPhone, open the Watch app, go to General > Software Update and upgrade to watchOS 9.0 or later
Caveat Standard OS upgrade considerations apply - verify critical apps are compatible with the new OS version before upgrading production devices
