CVE-2024-23258
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 · uneditedAn out-of-bounds read was addressed with improved input validation. This issue is fixed in macOS Sonoma 14.4, visionOS 1.1. Processing an 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 confidenceThis is an out-of-bounds read vulnerability in image processing components of macOS and visionOS. The vulnerability allows processing of specially crafted images to trigger the out-of-bounds read, which can be leveraged for arbitrary code execution. The fix implements improved input validation to prevent the out-of-bounds access.

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.
-
Check installed macOS versionRun 'sw_vers -productVersion' in Terminal or go to System Settings > General > AboutAffected if Version is 14.0, 14.1, 14.2, or 14.3 (any version >= 14.0 but < 14.4)
-
Check installed visionOS versionOn Apple Vision Pro, go to Settings > General > About > visionOSAffected if Version is 1.0.x (any version < 1.1)
-
Verify image processing is in useCheck for apps or services that process images: review running processes (Activity Monitor) for image editors, browsers, or Vision framework usageAffected if The system processes any images (the vulnerability is in core OS image components, so any image processing could trigger it)
-
Identify exposed image processing interfacesReview network services or APIs that accept image input: check for web servers, document converters, or automation tools that process image filesAffected if Untrusted or external images can be processed by the system
A system is affected if it runs macOS 14.0-14.3 or visionOS 1.0.x and processes images, since the out-of-bounds read exists in the core image processing components of those OS versions.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.114.4
Apply the vendor-supplied security updates: macOS Sonoma 14.4 or later, visionOS 1.1 or later. Prioritize systems that process untrusted or external images.
macOS Sonoma 14.4 or later; visionOS 1.1 or later
- Check current macOS version by selecting Apple menu > About This Mac
- If running macOS 14.0-14.3, update to macOS Sonoma 14.4 or later via System Settings > Software Update
- For visionOS devices, check current version in Settings > General > About
- If running visionOS version earlier than 1.1, update to visionOS 1.1 or later via Settings > General > Software Update
- After updating, verify the installation was successful and the system is running the patched version
