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
An out-of-bounds read was addressed with improved input validation. This issue is fixed in tvOS 14.3, macOS Big Sur 11.1, Security Update 2020-001 Catalina, Security Update 2020-007 Mojave, iOS 14.3 and iPadOS 14.3, iCloud for Windows 12.0, watchOS 7.2. Processing a maliciously crafted image may lead to heap corruption.

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 confidence

An out-of-bounds read vulnerability in Apple's image processing components allows heap corruption when processing a maliciously crafted image file. The vulnerability is caused by insufficient input validation during image parsing, leading to memory corruption that could be exploited for arbitrary code execution.

MitigationApply the available security updates: iOS 14.3/iPadOS 14.3, macOS Big Sur 11.1/Catalina Security Update 2020-001/Mojave Security Update 2020-007, tvOS 14.3, watchOS 7.2, and iCloud for Windows 12.0.

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 product in use
    Determine whether the system is running macOS, iOS, iPadOS, tvOS, watchOS, or iCloud for Windows. On macOS, go to Apple menu > About This Mac. On iOS/iPadOS, go to Settings > General > About. On tvOS/watchOS, go to Settings > General > About. For iCloud, check the iCloud application version on Windows.
    Affected if Any Apple product from the affected list is in use.
  2. Check the installed macOS version
    On macOS, run 'sw_vers' in Terminal or check Apple menu > About This Mac. Note the exact version number (e.g., 11.0.1, 10.15.7, 10.14.6).
    Affected if The version is: macOS Big Sur 11.0 to 11.0.x before 11.1; macOS Catalina 10.15.0 to 10.15.7 (including 10.15.7); macOS Mojave 10.14.0 to 10.14.6 (including 10.14.6).
  3. Check the installed iOS or iPadOS version
    On iPhone or iPad, go to Settings > General > About and note the version number (e.g., 14.2, 14.2.1).
    Affected if The version is iOS or iPadOS earlier than 14.3.
  4. Check the installed tvOS or watchOS version
    On Apple TV, go to Settings > General > About > Version. On Apple Watch, go to Settings > General > About > Watch Version. Note the version number.
    Affected if The version is tvOS earlier than 14.3 or watchOS earlier than 7.2.
  5. Check the installed iCloud for Windows version
    Open iCloud for Windows, click the menu or gear icon, and check About iCloud, or open Programs and Features in Windows Control Panel and find iCloud.
    Affected if The version is iCloud for Windows earlier than 12.0.

The environment is affected if any Apple product listed is installed and its version falls within the affected ranges: iCloud < 12.0, iPadOS < 14.3, iOS < 14.3, macOS (including older Mac OS X naming) versions 10.14.x up to 10.14.6, 10.15.x up to 10.15.7, or 11.0.x up to 11.0.x before 11.1, tvOS < 14.3, or watchOS < 7.2.
