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 execute arbitrary code 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 EMF images. 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 vulnerability to execute code in the context of the current process. Was ZDI-CAN-16371.

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

CorelDRAW Graphics Suite 23.5.0.506 contains an out-of-bounds read vulnerability in its EMF image parser. The lack of proper validation of user-supplied data during EMF parsing allows reading past the end of an allocated buffer, which can be leveraged for arbitrary code execution in the context of the current process. Exploitation requires user interaction via malicious file or webpage.

MitigationAvoid opening untrusted EMF files or visiting malicious pages until vendor patches are available. Consider deploying endpoint detection and monitoring for suspicious EMF processing activity.

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 CorelDRAW version
    Open CorelDRAW, go to Help > About CorelDRAW, or check the installed version in Programs and Features. Compare the version number to 24.2.1 - any version below 24.2.1 is affected.
    Affected if Installed version is lower than 24.2.1
  2. Confirm EMF import capability
    Check if the EMF (Enhanced Metafile) import filter is present and enabled. Attempt to import a standard EMF file into CorelDRAW to confirm the parser is functional.
    Affected if EMF import feature is available and operational in the installation
  3. Review recent EMF file access
    Examine Windows Event Logs, CorelDRAW audit logs (if enabled), or filesystem metadata for recently opened EMF files, especially from untrusted or unknown sources.
    Affected if Users have opened suspicious EMF files from untrusted sources
  4. Check for related processes
    Monitor for coreldraw.exe processes handling EMF files. Review any crash dumps or error reports related to EMF parsing in Windows Error Reporting or application logs.
    Affected if Crashes or errors occur when processing EMF files, indicating potential exploitation attempts

The environment is affected if CorelDRAW Graphics Suite version is below 24.2.1 and users can process EMF files, which is the default behavior.
