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 corruption issue was addressed with improved input validation. This issue is fixed in iOS 12.3, macOS Mojave 10.14.5, tvOS 12.3, watchOS 5.2.1, iTunes for Windows 12.9.5, iCloud for Windows 7.12. A maliciously crafted SQL query 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 confidence

A memory corruption vulnerability in Apple's SQL database handling components allowed remote attackers to execute arbitrary code via maliciously crafted SQL queries. The vulnerability affected multiple Apple products (iOS, macOS, tvOS, watchOS, iTunes, iCloud for Windows) and was addressed through improved input validation.

MitigationApply the available security updates: iOS 12.3, macOS Mojave 10.14.5, tvOS 12.3, watchOS 5.2.1, iTunes 12.9.5 for Windows, and iCloud 7.12 for Windows. Prioritize internet-facing systems and those processing untrusted SQL input.

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 installed Apple products on the system
    Check for iTunes, iCloud for Windows, or Apple Device Support in installed programs (Windows: Control Panel > Programs and Features, or via PowerShell: Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion)
    Affected if Any Apple software (iTunes, iCloud for Windows) is installed on a Windows system
  2. Check iTunes version on Windows
    Open iTunes, go to Help > About iTunes, or check Program Files\iTunes\iTunes.exe version property
    Affected if iTunes version is lower than 12.9.5
  3. Check iCloud for Windows version
    Open iCloud, click the gear icon > About iCloud, or locate iCloud.exe version in Program Files
    Affected if iCloud for Windows version is lower than 7.12, or between 10.0 and 10.4 inclusive
  4. Check macOS version on Apple computers
    Click Apple menu > About This Mac, or run 'sw_vers' in Terminal
    Affected if macOS version is lower than 10.14.5 (Mojave)
  5. Check iOS/tvOS/watchOS version on devices
    On iOS: Settings > General > About > Version; on tvOS: Settings > General > About > Version; on Apple Watch: On Watch app on iPhone > General > About
    Affected if iOS is lower than 12.3, tvOS is lower than 12.3, or watchOS is lower than 5.2.1

A system is affected if any Apple product listed above is installed and its version falls within the vulnerable ranges, particularly when processing untrusted SQL input through Apple's database components.
