CVE-2024-20793
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 versions 28.4, 27.9.3 and earlier are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. 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.

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.
-
Check installed Adobe Illustrator versionOpen Adobe Illustrator, go to Help > About Adobe Illustrator (or Illustrator > About Illustrator on Mac). The version number is displayed in the dialog. Alternatively, check via Control Panel > Programs and Features on Windows or Applications folder on Mac.Affected if The version shown is 28.4, 27.9.3, or any version earlier than these (including all 28.0-28.3.x versions and all 27.x versions below 27.9.4).
-
Confirm version is within affected rangeCompare your installed version number against these vulnerable ranges: versions >= 28.0 and < 28.5, OR versions < 27.9.4. Note that versions 27.9.4 and 28.5 and later are patched.Affected if Your version falls within < 27.9.4 OR >= 28.0 but < 28.5.
-
Understand exploitation requirementRecognize that this vulnerability is triggered when a user opens a specially crafted malicious file. There is no special configuration or feature that makes the application vulnerable - the flaw exists in the software code itself.Affected if You run any affected version of Adobe Illustrator and open files from untrusted sources.
You are affected if your installed Adobe Illustrator version is 28.4, 27.9.3, or any earlier version, or falls between 28.0 and 28.4 (exclusive of the patched 28.5 and later releases).
Generated from the published advisory. Verify against your own configuration.
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 · scoped27.9.428.5
Update Adobe Illustrator to a patched version beyond 28.4/27.9.3. Additionally, educate users to avoid opening files from untrusted sources, as exploitation requires user interaction.
Illustrator 28.5 or later (or 27.9.4 or later for the 27.x branch)
- 1. Open Adobe Creative Cloud desktop application or navigate to adobe.com/downloads
- 2. Locate Adobe Illustrator in your installed applications
- 3. Check the current installed version (Help > About Illustrator on Windows, or Illustrator > About Illustrator on macOS)
- 4. If version is < 27.9.4 or >= 28.0 and < 28.5, an update is required
- 5. In Adobe Creative Cloud, click the Updates button or find the update option for Illustrator
- 6. Download and install the latest version (28.5 or later for 28.x branch, or 27.9.4 or later for 27.x branch)
- 7. Restart Illustrator after the update completes
- 8. Verify the new version by checking Help > About Illustrator
