CVE-2014-125019
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, was found in FFmpeg 2.0. This affects the function decode_nal_unit of the component Slice Segment Handler. The manipulation leads to memory corruption. It is possible to initiate the attack 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 · high confidenceA memory corruption vulnerability exists in FFmpeg 2.0's decode_nal_unit function within the Slice Segment Handler component. The vulnerability allows manipulation of NAL (Network Abstraction Layer) unit parsing during video slice decoding, leading to memory corruption that could be exploited remotely via specially crafted media files.

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.
-
Confirm FFmpeg installationRun 'ffmpeg -version' or check for ffmpeg binary in common locations (/usr/bin/ffmpeg, /usr/local/bin/ffmpeg, etc.)Affected if FFmpeg is not installed on the system
-
Identify installed FFmpeg versionExecute 'ffmpeg -version' and parse the version string from the outputAffected if The version reported is exactly 2.0
-
Determine if video decoding features are in useCheck if the system processes H.264 or HEVC video files, or run 'ffmpeg -codecs' to list supported decoders; NAL unit parsing is specific to these formatsAffected if H.264/HEVC decoding is actively used with FFmpeg 2.0
-
Inspect media processing workflowsReview any automated media processing scripts, services, or tools that invoke FFmpeg to process untrusted input filesAffected if Untrusted media files are processed by FFmpeg 2.0
-
Audit for indicators of compromiseReview system logs, network logs, and any captured media files for anomalies; check for unexpected memory behavior or crashes during video processingAffected if Unusual logs or crash reports exist related to video decoding operations
A system is affected only if FFmpeg version 2.0 is installed AND it processes media files, particularly H.264/HEVC video content.

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 official patch to fix the bounds checking/validation issue in decode_nal_unit, or upgrade to a patched version of FFmpeg. Implement input validation on media files before processing to mitigate risk of exploitation.
