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
Pexip Infinity before 27.3 allows remote attackers to trigger excessive resource consumption via H.264.

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 confidence

Pexip Infinity before version 27.3 contains a denial-of-service vulnerability where specially crafted H.264 video packets can trigger excessive resource consumption on the server, potentially rendering the video conferencing service unavailable.

MitigationUpgrade Pexip Infinity to version 27.3 or later to remediate the vulnerability. If immediate patching is not possible, consider rate limiting or restricting untrusted H.264 video sources at the network perimeter.

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. Identify Pexip Infinity version
    Access the Pexip Infinity admin interface or use the command line to retrieve the installed software version
    Affected if The installed version cannot be confirmed as 27.3 or later
  2. Confirm H.264 video codec is in use
    Review the conference configuration or call logs to verify that H.264 video processing is enabled
    Affected if H.264 is enabled and the version is below 27.3
  3. Check for external H.264 video sources
    Inspect network settings and conferencing rules to determine if untrusted or external participants can send H.264 video streams
    Affected if External video sources are allowed and the version is below 27.3

The environment is affected if the Pexip Infinity version is below 27.3 and H.264 video processing is enabled, as specially crafted H.264 packets can trigger the DoS condition.
