# sox_ng: VOC file parser out-of-bounds write allows remote memory corruption

Link for people: https://infrastack.ai/live/CVE-2026-129264 (this .md is for agents)

sox_ng, a fork of the SoX audio tool, has an out-of-bounds write in its VOC decoder (read_samples_voc in src/voc.c). A crafted VOC audio file can trigger the write remotely, and the exploit has been disclosed publicly.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Installed sox_ng version at or below `14.8.1`
- Whether the VOC decoder (src/voc.c) is reached when processing files from untrusted sources

## Fix

- sox_ng: apply patch `0b40408b`; the sources give no fixed version number

## Timeline

- 2026-11-14T17:31:24+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-129264

## From the sources

A security vulnerability has been detected in sox_ng up to 14.8.1. Affected by this issue is the function read_samples_voc of the file src/voc.c of the component VOC Decoder. Such manipulation leads to out-of-bounds write. The attack can be executed remotely. The exploit has been disclosed publicly and may be used. The name of the patch is 0b40408b. A patch should be applied to remediate this issue. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.
