- AllPlayer: 7.4

## Description

AllPlayer 7.4 contains a local buffer overflow vulnerability in URL handling that allows attackers to overwrite structured exception handling pointers by supplying an excessively long URL string. Attackers can craft a malicious URL, paste it into the Open URL dialog, and trigger SEH-based code execution to run arbitrary commands with user privileges.

## What to do

- Check your stack: if you ship or depend on AllPlayer, no fixed version is listed yet; follow the vendor advisory per the references below.
