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
CoreGraphics in Apple iOS before 8.4 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted ICC profile in a PDF document, a different vulnerability than CVE-2015-3723.

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 CoreGraphics (iOS before 8.4) allows remote code execution or denial of service via a crafted ICC profile embedded in a PDF document. When iOS processes a maliciously constructed ICC color profile within a PDF, it triggers memory corruption that can be leveraged for arbitrary code execution.

MitigationUpdate affected iOS devices to version 8.4 or later to patch the CoreGraphics vulnerability. Until updated, avoid opening PDF documents from untrusted sources.

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. Check the iOS version installed on the device
    Navigate to Settings > General > About > Version on the iOS device
    Affected if The version displayed is 8.3 or lower (e.g., 8.3, 8.2, 8.1, 8.0, 7.x)
  2. Confirm the device runs Apple iPhone OS
    Navigate to Settings > General > About > Model to verify the device is an iOS device
    Affected if The device is an iPhone, iPad, or iPod touch running iOS
  3. Verify CoreGraphics component is present
    CoreGraphics is a core framework included in all iOS installations; confirm by checking that basic graphic rendering functions work on the device
    Affected if The device can render graphics, which confirms CoreGraphics is present and active

The device is affected if it runs iOS version 8.3 or lower, since the vulnerability exists in CoreGraphics on those versions and is triggered when processing PDF documents with embedded ICC profiles.
