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
Improper Input Validation vulnerability in GStreamer integration of The Document Foundation LibreOffice allows an attacker to execute arbitrary GStreamer plugins. In affected versions the filename of the embedded video is not sufficiently escaped when passed to GStreamer enabling an attacker to run arbitrary gstreamer plugins depending on what plugins are installed on the target system.

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

LibreOffice's GStreamer integration fails to properly sanitize/validate embedded video filenames before passing them to GStreamer, allowing an attacker to inject arbitrary GStreamer plugin commands through specially crafted filenames.

MitigationUpdate to a patched version of LibreOffice that implements proper input validation and escaping of filenames before passing them to GStreamer, or remove untrusted video files from documents.

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. Check installed LibreOffice version
    Run ' libreoffice --version ' or ' soffice --version ' to obtain the exact version number
    Affected if The version falls within 7.5.0 through 7.5.9, or 7.6.0 through 7.6.3
  2. Verify GStreamer support in LibreOffice
    Check if LibreOffice was built with GStreamer support by examining installed packages or running ' libreoffice --help ' for media-related options
    Affected if GStreamer integration is present and available for video handling in the installed LibreOffice build
  3. Confirm the operating system version
    Run ' cat /etc/os-release ' or ' cat /etc/fedora-release ' to identify the OS
    Affected if Running Fedora 38, Debian 11.0, or Debian 12.0 with the affected LibreOffice versions installed
  4. Identify if video embedding feature is used
    Inspect documents for embedded video objects or check if the user routinely inserts video files into LibreOffice Writer, Impress, or Calc documents
    Affected if The user opens, edits, or creates LibreOffice documents containing embedded or inserted video files from untrusted sources

A user is affected if they are running LibreOffice versions 7.5.0-7.5.9 or 7.6.0-7.6.3 on Fedora 38, Debian 11, or Debian 12, and they open or insert documents containing video files with specially crafted filenames that could be passed to GStreamer.

Upgrade available Upgrade to 7.5.9 / 7.6.3 or later
Fixed in 7.5.97.6.3
Interim mitigation

Update to a patched version of LibreOffice that implements proper input validation and escaping of filenames before passing them to GStreamer, or remove untrusted video files from documents.

Recommended fix High confidence

LibreOffice 7.5.9 (or later in 7.5.x branch) / LibreOffice 7.6.3 (or later in 7.6.x branch)

  1. Check your current LibreOffice version by opening LibreOffice and going to Help > About LibreOffice
  2. For Fedora 38 users: Run 'sudo dnf update' to receive the latest security updates including LibreOffice fixes
  3. For Debian 11/12 users: Run 'sudo apt update && sudo apt upgrade' to receive the fixed LibreOffice packages
  4. Alternatively, download LibreOffice 7.5.9 or later (7.5.x branch) from the official LibreOffice website: https://www.libreoffice.org/download/download/
  5. Alternatively, download LibreOffice 7.6.3 or later (7.6.x branch) from the official LibreOffice website
  6. After upgrading, verify the version by checking Help > About LibreOffice to confirm you are on version 7.5.9+, 7.6.3+, or later
Caveat Minor - standard version upgrade within same major release branch; review release notes for any new features or behavior changes
