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
Heap Buffer Overflow vulnerability in DumpTS v0.1.0-nightly allows attackers to cause a denial of service via the function PushTSBuf() at /src/PayloadBuf.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 heap buffer overflow vulnerability exists in DumpTS v0.1.0-nightly within the PushTSBuf() function in /src/PayloadBuf.cpp. The vulnerability allows attackers to overflow heap-allocated buffers, leading to potential denial of service through application crash or undefined behavior.

MitigationUpdate DumpTS to a patched version if available, or apply bounds checking and proper buffer size validation in the PushTSBuf() function to prevent heap overflow 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. Identify if DumpTS is installed
    Search for the DumpTS binary or library on the system using 'which dumpts' or 'find / -name dumpts 2>/dev/null' on Linux, or check Program Files on Windows
    Affected if DumpTS executable or library is found on the system
  2. Determine the installed version
    Run 'dumpts --version' or 'dumpts -v' to retrieve the version string, or check the binary's metadata/version info
    Affected if The version displays as v0.1.0-nightly or contains 'nightly' without a patched version indicator
  3. Locate the vulnerable PayloadBuf.cpp component
    Check if the binary links to or includes a library containing /src/PayloadBuf.cpp by running 'ldd dumpts' on Linux or checking dependencies on Windows
    Affected if The application links against the vulnerable PayloadBuf component from v0.1.0-nightly
  4. Inspect runtime behavior with large input
    Monitor heap allocations during typical DumpTS operations using process memory tools; heap buffer overflows may manifest as crashes or memory corruption warnings
    Affected if The application crashes with heap corruption errors or exhibits undefined behavior when processing typical transport stream inputs

A user is affected if DumpTS v0.1.0-nightly is installed and the PushTSBuf() function in PayloadBuf.cpp is executed during normal operation.

Mitigation

Update DumpTS to a patched version if available, or apply bounds checking and proper buffer size validation in the PushTSBuf() function to prevent heap overflow conditions.
