CVE-2022-40884
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 · uneditedBento4 1.6.0 has memory leaks via the mp4fragment.
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 confidenceBento4 1.6.0 contains a memory leak vulnerability in the mp4fragment tool. The memory leak occurs during the fragmentation processing of MP4 files, where allocated memory is not properly released, leading to resource exhaustion over time.

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 Bento4 installationRun 'mp4fragment --version' or 'mp4fragment --help' to see the version information. On systems where Bento4 is installed as a package, check the package manager (e.g., 'dpkg -l | grep bento4' or 'rpm -qa | grep bento4').Affected if The installed version is exactly 1.6.0
-
Locate the mp4fragment executableVerify the mp4fragment binary exists on the system using 'which mp4fragment' or by searching common installation directories such as /usr/bin, /usr/local/bin, or the Bento4 installation path.Affected if The mp4fragment tool is present on the system
-
Check for active or scheduled mp4fragment processesUse commands like 'ps aux | grep mp4fragment' or review cron jobs and automation scripts that may invoke mp4fragment for MP4 file processing.Affected if mp4fragment is actively used or scheduled to run, especially on multiple or large MP4 files
-
Monitor memory behavior during mp4fragment executionRun mp4fragment on a test MP4 file while monitoring memory usage with tools like 'top', 'htop', or 'ps' (e.g., 'mp4fragment input.mp4 output.mp4 &' then observe RSS memory of the process).Affected if Memory usage of the mp4fragment process continuously grows without returning to baseline after processing completes
A system is affected if Bento4 version 1.6.0 is installed AND the mp4fragment tool is used to process MP4 files, with memory consumption growing unbounded during fragmentation operations.

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 dataUpgrade to a patched version of Bento4 if available, or avoid prolonged use of the mp4fragment tool to limit exposure to the memory leak.
