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
JetBrains YouTrack before 2020.1.659 was vulnerable to DoS that could be caused by attaching a malformed TIFF file to an issue.

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

A denial-of-service vulnerability exists in JetBrains YouTrack's image processing functionality. When a malformed TIFF file is attached to an issue, the TIFF parser crashes or enters an infinite loop, causing the YouTrack service to become unresponsive. This affects all versions prior to 2020.1.659.

MitigationUpgrade YouTrack to version 2020.1.659 or later to receive the patch for the TIFF parsing vulnerability. If immediate upgrading is not feasible, consider restricting TIFF file attachments until the upgrade can be performed.

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. Determine installed YouTrack version
    Log in as administrator and navigate to Administration > About, or check the version from the installation directory's version.xml or startup logs
    Affected if version is below 2020.1.659
  2. Verify file attachment feature is enabled
    Check if users have permission to attach files to issues via Administration > Groups > Permissions > Attaching files
    Affected if file attachments are permitted for users
  3. Confirm TIFF file uploads are allowed
    Review the allowed attachment file types in Administration > System > File types; check if .tiff or .tif extensions are listed
    Affected if TIFF file extensions are among permitted attachment types

You are affected if your YouTrack version is below 2020.1.659 AND the file attachment feature allows TIFF files to be uploaded to issues.
