No fixed build or workaround is published yet. Limit exposure and watch for a patch.

Steps

Written by AI from the record

Check whether you have “Sound eXchange (SoX) 14.4.2” installed on any server/workstations that convert audio.
If you do use it, identify where audio files come from (customer uploads, email attachments, public downloads) and whether untrusted files can be processed.
If you find you’re on 14.4.2, stop processing untrusted “.snd” files (or any unknown audio) until you can upgrade or apply a mitigation.
Contact your software vendor/hosting provider or your internal IT team to get an update path; no fixed version information was found for this CVE.
Until patched, restrict who can supply files and add controls so only trusted sources can reach the converter.

What it is

From the CVE record

The wavwritehdr 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 snd file, during conversion to a wav file.

In plain language

Written by AI from the record

CVE-2017-11359 is a crash bug in SoX Sound eXchange (Sound eXchange) 14.4.2 that can be triggered by a specially crafted sound file; if your business converts untrusted audio, you should act to reduce the risk.

CVE-2017-11359 is a denial-of-service issue (CWE-369) in the wavwritehdr function in Sound eXchange (SoX) where a crafted input sound file can trigger a divide-by-zero and crash the converter—attackers typically need you to process the malicious file.

If you're affected

Service outage during conversion
Business workflow disruption
Potential job/process termination
Lost time handling failed conversions

What is it

This vulnerability is like a “bad file” that can make the audio conversion program crash. If your business uses SoX Sound eXchange to turn customer or internet-provided sound files into WAV, an attacker can potentially send a crafted file that knocks out the conversion process.

Who is affected

This matters if you use “Sound eXchange (SoX)”—especially version 14.4.2—to convert sound files as part of your operations. It’s mainly a risk when untrusted users can provide files for conversion, since the crash happens when processing a crafted input sound file.

How urgent is it

This is an AMBER priority: it can cause an application crash, disrupting audio conversion work, but there’s no confirmed exploitation listing from CISA (KEV not listed). There is a public exploit available, so you should treat it as actionable if your business processes untrusted audio files. If you don’t handle untrusted inputs, the risk is much lower.

What to do — in detail

Confirm exposure

Find all places SoX Sound eXchange is installed and used (servers, batch processing machines, desktop workflows, containers).
Check the installed version; focus on whether it is Sound eXchange (SoX) 14.4.2.

Identify exposure path

Determine how audio files enter your system:
- Customer uploads (web portal, email attachments, ticketing)
- Files downloaded from the internet
- Any automated pipelines that process “incoming” audio without strict trust controls
The practical risk is when attackers can cause your system to process a crafted file (the issue is triggered during conversion).

Upgrade / fixed version status

The provided findings indicate no fix/patch information is available for this CVE.
Because no fixed version is known from the supplied materials, the remediation path should be handled by your vendor/IT team: request the recommended upgrade target or an internal patch/workaround.

Temporary mitigations (while waiting for a fix)

Block or quarantine untrusted source formats: do not process unknown/untrusted “.snd” files.
Apply strict allowlists: only accept audio from trusted sources or pre-validated workflows.
Add isolation: run the conversion service in a restricted environment (limited permissions) so a crash doesn’t take down other critical systems.

What to monitor

Conversion job failures and application crashes tied to audio processing.
Repeated failures shortly after receiving a specific file/user/source.

Due date

No CISA KEV due date applies here because this CVE is not listed in CISA KEV per the provided findings.

Technical context

CVE-2017-11359 affects Sound eXchange (SoX), specifically the wavwritehdr function in wav.c. The weakness is CWE-369 (divide-by-zero), and the observed impact is a denial of service: a crafted sound file can trigger a divide-by-zero and crash the converter during conversion to WAV.

Exploitation status: a public exploit exists (weaponization finding notes 1 known public exploit). However, it is not listed in CISA KEV, so there is no confirmation of widespread exploitation via that channel in the provided materials.

Fix availability: no fixed version/patch details were available in the findings provided, so remediation must rely on contacting the maintainer/vendor for an upgrade recommendation or applying a mitigative process isolation/validation approach.

EPSS/likelihood: a predicted EPSS value was provided, but this is a prediction and is not used as a deciding factor over confirmed exploitation; additionally, no KEV confirmation is present in the findings.

This is a general assessment based on public vulnerability data. It does not account for your specific infrastructure — when in doubt, consult a security specialist.
