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
Illustrator versions 29.8.4, 30.1 and earlier are affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

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

Adobe Illustrator versions 29.8.4, 30.1 and earlier contain an out-of-bounds write vulnerability when parsing specially crafted malicious files. Successful exploitation allows arbitrary code execution in the context of the current user, requiring the victim to open the malicious file.

MitigationUsers should refrain from opening untrusted or unexpected Illustrator files and should update to a patched version of Adobe Illustrator as soon as vendor updates become available.

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. Verify Adobe Illustrator is installed
    Check for the presence of Adobe Illustrator application - on Windows look in Program Files/Adobe or via Add/Remove Programs; on macOS check /Applications for Adobe Illustrator.app
    Affected if Adobe Illustrator is present on the system
  2. Retrieve installed Illustrator version on Windows
    Open Programs and Features, find Adobe Illustrator, and note the version shown, or query the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{AC76BA86-1033-FFFF-7760-0C0C0C0C0C8} (or similar Adobe registry entry) for DisplayVersion
    Affected if Version retrieved is within the affected ranges
  3. Retrieve installed Illustrator version on macOS
    Right-click Adobe Illustrator.app in Applications, select Get Info, and read the Version field under General, or run: defaults read "/Applications/Adobe Illustrator 2024.app/Contents/Info.plist" CFBundleVersion (adjust app name for version year)
    Affected if Version retrieved is within the affected ranges
  4. Compare version against affected ranges
    Compare your installed version number to the affected ranges: 29.0 through 29.8.4, or 30.0 through 30.1 - any version matching these ranges is vulnerable
    Affected if Installed version is 29.0, 29.1, 29.2, 29.3, 29.4, 29.5, 29.6, 29.7, 29.8, 29.8.1, 29.8.2, 29.8.3, 29.8.4, 30.0, 30.1, or any 29.x version below 29.8.5, or any 30.x version below 30.2

If Adobe Illustrator is installed and its version falls within 29.0 to 29.8.4 or 30.0 to 30.1, the system is vulnerable and could be exploited by opening a malicious Illustrator file.

Interim mitigation

Users should refrain from opening untrusted or unexpected Illustrator files and should update to a patched version of Adobe Illustrator as soon as vendor updates become available.

Recommended fix High confidence

Adobe Illustrator 29.8.5 (for version 29.x) or Adobe Illustrator 30.2 (for version 30.x)

  1. Verify current Adobe Illustrator version by opening the application and navigating to Help > About Adobe Illustrator
  2. Close Adobe Illustrator completely before updating
  3. Open Adobe Creative Cloud desktop application
  4. Navigate to the Apps section
  5. Find Adobe Illustrator in the list of installed apps
  6. Click on Update to install the latest version
