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 · uneditedIllustrator is 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 · moderate confidenceAdobe Illustrator contains an out-of-bounds write vulnerability that allows memory corruption beyond allocated buffer boundaries. Successful exploitation permits arbitrary code execution within the context of the user who opened the malicious file. The vulnerability requires victim interaction, specifically opening a crafted malicious file.

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.
-
Verify Adobe Illustrator is installedCheck for Adobe Illustrator installation: On Windows, look in C:\Program Files\Adobe\Adobe Illustrator [Version] or check Programs and Features. On macOS, check /Applications for Adobe Illustrator.appAffected if Adobe Illustrator is present on the system
-
Retrieve installed version numberOn Windows, right-click the application in Programs and Features and select Properties, or run 'Get-ItemProperty' in PowerShell for the Illustrator.exe path. On macOS, right-click Adobe Illustrator.app and select Get Info to view the versionAffected if Unable to determine the version number
-
Compare version against first affected rangeCheck if the installed version is >= 29.0 and < 29.8.9. For example, versions 29.0 through 29.8.8 are affectedAffected if Version falls within 29.0 to 29.8.8 inclusive
-
Compare version against second affected rangeCheck if the installed version is >= 30.0 and < 30.6. For example, versions 30.0 through 30.5 are affectedAffected if Version falls within 30.0 to 30.5 inclusive
The system is affected if Adobe Illustrator is installed and the version number falls within 29.0-29.8.8 or 30.0-30.5, since these ranges contain the out-of-bounds write vulnerability exploitable via malicious files.

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 · scoped29.8.930.6
Apply the official Adobe security patch for Illustrator when available. Until then, exercise caution by not opening files from untrusted sources and consider restricting file handling privileges for the application.
Adobe Illustrator 29.8.9 or 30.6 (or later)
- Close Adobe Illustrator if it is currently running
- Update Adobe Illustrator to version 29.8.9 or later for the 29.x branch, or version 30.6 or later for the 30.x branch
- Restart Illustrator after the update
- Verify the installed version matches the fixed release (Help > About Adobe Illustrator)
