CVE-2019-25617 in Ease Audio Converter
Summary
by MITRE • 03/22/2026
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.

The vulnerability identified as CVE-2019-25617 resides within Ease Audio Converter version 5.30, specifically within its Audio Cutter functionality. This represents a classic buffer overflow condition that manifests as a denial of service attack vector. The flaw occurs when the application processes malformed MP4 files through its audio cutting interface, creating a scenario where maliciously crafted media files can cause the software to crash or become unresponsive. The vulnerability is particularly concerning because it operates at the file parsing level, meaning that any user who interacts with the Audio Cutter feature and loads an improperly formatted MP4 file will trigger the exploitable condition.
From a technical perspective, the vulnerability stems from inadequate input validation and buffer management within the MP4 file parser component of the audio conversion software. When the application encounters an oversized buffer within the MP4 file structure, it fails to properly handle the memory allocation and data processing, leading to a segmentation fault or similar memory corruption error. This type of vulnerability maps directly to CWE-121, which describes stack-based buffer overflow conditions, and CWE-122, which covers heap-based buffer overflow scenarios. The attack vector is particularly accessible as it requires only local user interaction through the application interface, making it a low-barrier exploit for malicious actors within the system.
The operational impact of this vulnerability extends beyond simple application instability, as it represents a potential gateway for more sophisticated attacks within the system. Local attackers who can manipulate the audio conversion workflow can cause repeated application crashes, potentially leading to system instability or denial of service for legitimate users. The vulnerability affects the availability aspect of the system's security triad, as it can be exploited to prevent normal operation of the audio conversion software. From an ATT&CK framework perspective, this vulnerability aligns with techniques involving process injection and privilege escalation, as successful exploitation could potentially allow attackers to execute arbitrary code within the application context or leverage the crash to perform more complex attacks.
Mitigation strategies for CVE-2019-25617 should focus on immediate software updates and input validation improvements. Users should upgrade to the latest version of Ease Audio Converter where the vulnerability has been patched, as the vendor has likely implemented proper buffer size checking and memory management protocols. Additionally, system administrators should consider implementing application whitelisting policies that restrict the execution of potentially vulnerable software, particularly in enterprise environments where multiple users interact with multimedia conversion tools. Network segmentation and monitoring should also be enhanced to detect unusual patterns of application crashes or file processing activities that might indicate exploitation attempts. The vulnerability also highlights the importance of input sanitization and proper error handling in multimedia processing applications, as similar issues could exist in other file format parsers within the same software ecosystem or related applications.
