Description

The startread function in wav.c in Sound eXchange (SoX) 14.4.2 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted wav file.

In plain language

AI Worth attention

CVE-2017-11332 is a SoX (Sound eXchange) bug where a specially crafted WAV audio file can crash the program when it’s opened—if your business accepts or processes user-supplied WAV files, you should act, otherwise the risk is lower.

Executive summary

CVE-2017-11332 is a denial-of-service issue in SoX’s `startread` function for WAV handling (CWE-369 divide-by-zero), where a malformed WAV file can trigger a crash when the file is processed; it is reachable by remote attackers through supplying a crafted audio file (no authentication needed, but user interaction is required).

If affected, business impact
Service outages from crashesProcessing pipeline disruptionLoss of audio conversion availabilityPotential workflow downtime

What to do now

  1. Check whether Sound eXchange (SoX) is installed and note its version (run sox --version and also check any container/VM images your service uses).
  2. Identify where WAV files are handled (uploads, email attachments, imports, automated conversion jobs) and confirm whether untrusted users can cause SoX to open them.
  3. Block or quarantine untrusted WAV inputs temporarily (e.g., reject WAV uploads, or only process WAV files that have been scanned/validated).
  4. If you can’t block WAVs, run the WAV-to-audio processing in a sandboxed, isolated environment so a crash can’t take down other services.
  5. Track for an upstream SoX fix and plan an upgrade as soon as a fixed SoX version is available, then re-test WAV handling with your normal workflows.
  6. Add monitoring for repeated SoX crashes when WAV files are processed, and review crash logs to see whether the issue matches CVE-2017-11332 symptoms.
