CVE-2025-50950

7.5 HIGH

📋 TL;DR

Audiofile v0.3.7 contains a NULL pointer dereference vulnerability in the ModuleState::setup function. This can cause denial of service (crash) when processing malicious audio files. Users and applications that process untrusted audio files with this library are affected.

💻 Affected Systems

Products:
  • Audiofile library
Versions: v0.3.7 specifically
Operating Systems: All platforms where Audiofile is used (Linux, Windows, macOS)
Default Config Vulnerable: ⚠️ Yes
Notes: Any application using Audiofile v0.3.7 to process audio files is vulnerable. The vulnerability is triggered when processing audio files.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Application crash leading to denial of service, potentially disrupting audio processing services or applications.

🟠

Likely Case

Application crash when processing specially crafted audio files, causing temporary service disruption.

🟢

If Mitigated

Minimal impact with proper input validation and sandboxing of audio file processing.

🌐 Internet-Facing: MEDIUM - Applications that accept audio uploads from untrusted sources could be targeted to cause service disruption.
🏢 Internal Only: LOW - Internal systems processing trusted audio files have minimal exposure.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires feeding a malicious audio file to the vulnerable library. No authentication is needed if the application accepts audio input.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: v0.3.8 or later

Vendor Advisory: https://github.com/mpruett/audiofile/issues/66

Restart Required: Yes

Instructions:

1. Update Audiofile to v0.3.8 or later. 2. Recompile any applications using Audiofile. 3. Restart affected services.

🔧 Temporary Workarounds

Input validation and sanitization

all

Implement strict validation of audio file inputs before processing

Sandbox audio processing

all

Run audio file processing in isolated containers or sandboxes

🧯 If You Can't Patch

  • Implement strict file type validation and reject suspicious audio files
  • Monitor for application crashes and implement automatic restart mechanisms

🔍 How to Verify

Check if Vulnerable:

Check if Audiofile v0.3.7 is installed: 'ldconfig -p | grep audiofile' or check package manager

Check Version:

dpkg -l | grep audiofile (Debian/Ubuntu) or rpm -qa | grep audiofile (RHEL/CentOS) or check with your package manager

Verify Fix Applied:

Verify Audiofile version is v0.3.8 or later: 'audiofile --version' or check installed package version

📡 Detection & Monitoring

Log Indicators:

  • Application crashes with segmentation fault or NULL pointer errors
  • Audio processing service restarts

Network Indicators:

  • Multiple failed audio file uploads followed by service disruption

SIEM Query:

source="application.logs" AND ("segmentation fault" OR "NULL pointer" OR "audiofile crash")
