CVE-2024-20798
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 28.3, 27.9.2 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.
dbcve analysis · high confidenceAdobe Illustrator versions 28.3, 27.9.2 and earlier contain an out-of-bounds read vulnerability that allows memory disclosure beyond allocated buffers when a user opens a maliciously crafted file. This memory disclosure can be leveraged to bypass ASLR (Address Space Layout Randomization) mitigations, potentially facilitating further exploitation.

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 the presence of Adobe Illustrator on the system. On Windows, look in Program Files/Adobe or check the registry under HKLM\SOFTWARE\Adobe. On macOS, check /Applications for Adobe Illustrator.Affected if Adobe Illustrator is present on the system
-
Determine installed version numberOpen Adobe Illustrator and navigate to Help > About Adobe Illustrator. Alternatively, on Windows check the file version of the executable (usually at C:\Program Files\Adobe\Adobe Illustrator [Version]\Support Files\Contents\Windows\Illustrator.exe). On macOS, right-click the app in /Applications and select Get Info to view the version.Affected if A version number is displayed
-
Compare version against affected rangesMatch your installed version to the following vulnerable ranges: version 27.x less than 27.9.3, or version 28.x from 28.0 through 28.3. Versions 27.9.3+ and 28.4+ are not affected.Affected if Installed version is 27.9.2 or earlier, OR installed version is 28.0, 28.1, 28.2, or 28.3
-
Confirm vulnerability trigger conditionThis vulnerability is triggered when opening a maliciously crafted file. Check if the application handles files from untrusted sources, as the flaw requires user interaction to open a specific malformed file.Affected if Users routinely open files from external or untrusted sources in Illustrator
User is affected if Adobe Illustrator version is 27.9.2 or earlier, or falls within 28.0-28.3, and the application is used to open files (including from untrusted sources).

dbcve · scoped27.9.328.4
Update Adobe Illustrator to version 28.4 or later. Avoid opening untrusted or unexpected files until the patch is applied.
Adobe Illustrator 27.9.3 (for 27.x line) or 28.4 (for 28.x line) or later
- Open Adobe Creative Cloud desktop application
- Navigate to the Apps section and locate Adobe Illustrator
- Click the Update button next to Illustrator to install the latest available version
- Alternatively, open Illustrator and go to Help > Check for Updates to trigger the update process
- Restart Illustrator after the update completes
- Verify the installed version by going to Help > About Adobe Illustrator - it should show version 27.9.3 or 28.4 (or later)
