CVE-2014-125008
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 classified as problematic has been found in FFmpeg 2.0. Affected is the function vorbis_header of the file libavformat/oggparsevorbis.c. The manipulation leads to memory corruption. It is possible to launch 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 · moderate confidenceMemory corruption vulnerability in the vorbis_header function within libavformat/oggparsevorbis.c of FFmpeg 2.0. The vulnerability occurs during Ogg Vorbis header parsing and can be exploited remotely, likely through 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.
-
Identify FFmpeg versionRun `ffmpeg -version` and examine the output for the version number, or check the binary/package metadataAffected if The version shown is exactly 2.0
-
Verify Ogg demuxer is availableRun `ffmpeg -formats 2>/dev/null | grep -i ogg` or `ffmpeg -demuxers 2>/dev/null | grep ogg` to confirm Ogg container support is compiled inAffected if The ogg demuxer is present and enabled
-
Verify Vorbis decoder is availableRun `ffmpeg -codecs 2>/dev/null | grep -i vorbis` or `ffmpeg -decoders 2>/dev/null | grep vorbis` to confirm Vorbis audio decoding is compiled inAffected if The vorbis decoder is present and enabled
-
Check for vulnerable code presenceInspect the libavformat/oggparsevorbis.c file in the FFmpeg source or library if accessible; verify the vorbis_header function exists and handles Ogg Vorbis headersAffected if The vulnerable oggparsevorbis component is present in the installation
The environment is affected if FFmpeg version 2.0 is installed with Ogg container and Vorbis decoder support enabled, allowing processing of Ogg Vorbis media files.

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 FFmpeg patch to fix the memory corruption issue, or upgrade to a patched version of FFmpeg beyond 2.0. Validate and sanitize Ogg Vorbis streams before processing.
