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 vulnerability, which was classified as problematic, has been found in FFmpeg 2.0. Affected by this issue is the function decode_slice_header. The manipulation leads to memory corruption. The attack may be launched remotely. It is recommended to apply a patch to fix this issue.
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 confidenceMemory corruption vulnerability in FFmpeg 2.0's decode_slice_header function during video stream processing. The vulnerability can be triggered by a specially crafted media file, leading to potential arbitrary code execution or denial of service.

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.
-
Check if FFmpeg is installedRun 'ffmpeg -version' or 'which ffmpeg' to verify FFmpeg is present on the systemAffected if FFmpeg is not installed or the command fails - not applicable
-
Identify the installed FFmpeg versionExecute 'ffmpeg -version' and parse the output to find the version number (e.g., 'ffmpeg version 2.0' or similar)Affected if The version displayed is exactly 2.0 (e.g., 2.0, 2.0.0, 2.0.1, etc.) - the environment is affected
-
Check for alternative version reportingRun 'ffmpeg -buildinfo' or check package manager (dpkg -l ffmpeg, rpm -qi ffmpeg) to confirm the exact version package installedAffected if The packaged version resolves to 2.0 series - likely affected
-
Verify if video processing is activeCheck for running processes that use FFmpeg for video decoding: 'ps aux | grep ffmpeg' or 'pgrep -a ffmpeg'Affected if FFmpeg 2.0 is actively processing video streams - the decode_slice_header function is in use and the system is vulnerable to specially crafted media files
If FFmpeg version 2.0 is installed and actively processing or capable of processing video streams, the environment is affected by CVE-2014-125018.

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 dataApply the vendor-supplied patch to fix the decode_slice_header function and rebuild FFmpeg. Ensure all systems running FFmpeg are updated to a patched version.
