CVE-2021-40732
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 · uneditedXMP Toolkit version 2020.1 (and earlier) is affected by a null pointer dereference vulnerability that could result in leaking data from certain memory locations and causing a local denial of service in the context of the current user. User interaction is required to exploit this vulnerability in that the victim will need to open a specially crafted MXF 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 confidenceXMP Toolkit versions 2020.1 and earlier contain a null pointer dereference vulnerability in MXF file parsing. When processing a specially crafted MXF file, the parser attempts to dereference a null pointer, causing memory data leakage from certain memory locations and resulting in a local denial of service. The exploit requires user interaction to open the malicious file, running in the context of the current user.

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.
-
Identify XMP Toolkit installationSearch for XMP Toolkit SDK files or libraries on the system. Common locations include /opt/adobe/xmp, /usr/lib/, or custom application directories. Look for files named libxmpmeta, XMP, or related libraries.Affected if XMP Toolkit SDK files or libraries are found on the system
-
Determine installed XMP Toolkit versionCheck version information in SDK documentation, library metadata, or application bundled files. Look for version files, resource info, or use strings command on libraries to find version strings like '2020.1' or earlier.Affected if The installed version is 2020.1 or any earlier version (e.g., 2019.x, 2018.x, etc.)
-
Verify MXF file processing capabilityDetermine if any installed applications or tools use XMP Toolkit for parsing MXF (Material eXchange Format) files. Check application documentation or configuration for MXF support.Affected if Applications with MXF parsing functionality via XMP Toolkit are present and configured for use
-
Check for Debian XMP Toolkit packageOn Debian systems, run: dpkg -l | grep -i xmp or dpkg -l | grep -i adobe to see if the XMP Toolkit package from Debian 10.0 is installed.Affected if The Debian XMP Toolkit package from version 10.0 is installed
You are affected if XMP Toolkit version 2020.1 or earlier (or Debian 10.0 XMP package) is installed and any application uses it to process MXF files.
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.
From vendor dataAvoid opening untrusted or unexpected MXF files from unverified sources. Apply vendor patches for XMP Toolkit when available, as this is an Adobe product vulnerability.
