CVE-2024-53309
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 · uneditedA stack-based buffer overflow vulnerability exists in Effectmatrix Total Video Converter Command Line (TVCC) 2.50 when an overly long string is passed to the "-f" parameter. This can lead to memory corruption, potentially allowing arbitrary code execution or causing a denial of service via specially crafted input.
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 confidenceA stack-based buffer overflow exists in Effectmatrix Total Video Converter Command Line (TVCC) 2.50 when processing an overly long string through the '-f' parameter. This causes memory corruption on the stack, potentially allowing an attacker to overwrite return addresses and achieve arbitrary code execution, or cause a denial of service via crash.

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.
-
Locate the TVCC executableSearch common installation directories (e.g., C:\Program Files\Effectmatrix, /usr/local/bin, /opt/tvcc) or use 'where tvcc' on Windows or 'which tvcc' on Linux to find the executableAffected if TVCC is found on the system
-
Determine the installed TVCC versionRun 'tvcc --version' or 'tvcc -v' from the command line and compare the output to version 2.50Affected if The reported version is exactly 2.50 or falls within the affected version range
-
Inspect automated scripts or configurations using the -f parameterSearch project files, scripts, configuration files, or cron jobs for occurrences of 'tvcc' combined with '-f' followed by a file path or string argumentAffected if The -f parameter is used in any automated or manual command execution
-
Check for unusually long string inputs to -fReview any scripts or logs that invoke TVCC with the -f flag; manually inspect whether any supplied string argument to -f exceeds typical path length expectations (e.g., hundreds or thousands of characters)Affected if Any command invokes TVCC with an excessively long string passed to the -f parameter
-
Test for crash behavior with long -f inputIf safe to do so in a non-production environment, execute 'tvcc -f [string_of_500_or_more_characters]' and observe whether the program crashes or exhibits unexpected behaviorAffected if The program crashes or hangs when given an abnormally long string via -f
A user is affected if TVCC version 2.50 is installed and the -f parameter is used with overly long string inputs, as this triggers the stack-based buffer overflow.

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 dataUpdate to the latest version of TVCC if a patch is available; otherwise, implement strict input length validation on the '-f' parameter and replace unsafe string functions with bounded alternatives throughout the parameter parsing code.
