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
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Corel CorelDRAW Graphics Suite 23.5.0.506. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PDF files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-16370.

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

This is an information disclosure vulnerability in CorelDRAW Graphics Suite's PDF parser. The vulnerability stems from insufficient validation of user-supplied data during PDF file parsing, allowing a read past the end of an allocated buffer. Exploitation requires user interaction (opening a malicious PDF file), and this flaw can be chained with other vulnerabilities to achieve arbitrary code execution.

MitigationUsers should avoid opening untrusted or unexpected PDF files from unverified sources. The vendor should patch the PDF parsing component to add proper bounds checking and validation of user-supplied data before reading operations.

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. Confirm CorelDRAW Graphics Suite is installed
    Open Windows Settings > Apps > Installed apps, or check Add/Remove Programs, and look for CorelDRAW Graphics Suite in the list of installed software.
    Affected if CorelDRAW Graphics Suite appears in the installed programs list.
  2. Identify the installed CorelDRAW version number
    Right-click the CorelDRAW executable (usually located in C:\Program Files\Corel\CorelDRAW Graphics Suite XX\Programs\CorelDRAW.exe), select Properties, and view the Details tab for the Product Version. Alternatively, open CorelDRAW and go to Help > About CorelDRAW.
    Affected if A version number is displayed (for example, 24.0, 24.1, or any version shown).
  3. Compare installed version against the vulnerable range
    Compare the identified version number to the vulnerable threshold. Versions prior to 24.2.1 are affected (for example, 24.0, 24.1.0, 23.5, etc.). Versions 24.2.1 and later are not vulnerable.
    Affected if The installed version is less than 24.2.1 (for example, 24.0.0.450, 23.5.0.301, etc.).
  4. Verify the PDF parsing feature is accessible
    Confirm that the PDF import or open functionality is available in the installed version. In CorelDRAW, attempt to import or open a PDF file via File > Open and verify PDF file type appears in the supported formats.
    Affected if The PDF file type is supported and can be opened in the installed version.

The environment is affected if CorelDRAW Graphics Suite is installed with a version lower than 24.2.1 and the PDF parsing feature can be used to open files.
