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
A NULL Pointer Dereference discovered in DumpTS v0.1.0-nightly allows attackers to cause a denial of service via the function DumpOneStream() at /src/DumpStream.cpp.

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

A NULL pointer dereference vulnerability exists in the DumpOneStream() function in DumpTS v0.1.0-nightly at /src/DumpStream.cpp. Attackers can trigger this condition to cause a denial of service by providing input that results in a NULL pointer being dereferenced without proper validation.

MitigationAdd NULL pointer validation checks in the DumpOneStream() function before dereferencing any pointers. Ensure all pointer variables are validated before use, and implement proper error handling for NULL conditions.

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. Locate the DumpTS binary
    Run 'which dumpts' or search for the executable in common directories like /usr/bin/, /usr/local/bin/, or search with 'find / -name dumpts -type f 2>/dev/null'
    Affected if The DumpTS executable is found on the system
  2. Identify the installed version
    Run 'dumpts --version' or 'dumpts -v' to display version information; compare against the affected version 0.1.0-nightly
    Affected if The version is 0.1.0-nightly or earlier
  3. Check for recent execution history
    Review shell history or system logs for commands that invoked dumpts, especially with input from untrusted sources
    Affected if Dumpts was recently used to process input files
  4. Inspect input validation behavior
    Test Dumpts with a minimal or malformed input file and observe if the program crashes or exhibits unexpected behavior indicating NULL pointer issues
    Affected if The program crashes when processing input without proper NULL validation in the DumpOneStream() function

A user is affected if DumpTS version 0.1.0-nightly is installed and used to process input files that trigger the NULL pointer dereference in the DumpOneStream() function.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Add NULL pointer validation checks in the DumpOneStream() function before dereferencing any pointers. Ensure all pointer variables are validated before use, and implement proper error handling for NULL conditions.
