CVE-2019-25562 in Convert Video jetAudio
Summary
by MITRE • 03/21/2026
jetAudio 8.1.7 contains a buffer overflow vulnerability in the video converter component that allows local attackers to crash the application by supplying an oversized string in the File Naming field. Attackers can paste a malicious buffer of 512 bytes into the File Naming parameter and trigger the crash by clicking the Preview button, causing a denial of service.

The vulnerability identified as CVE-2019-25562 resides within jetAudio version 8.1.7, specifically within its video converter component. This represents a classic buffer overflow flaw that demonstrates poor input validation practices in multimedia processing software. The vulnerability manifests when the application processes user-supplied data in the File Naming field, which is commonly used to specify output filenames during video conversion operations. The flaw occurs because the application fails to properly validate the length of input data before copying it into a fixed-size buffer, creating an exploitable condition that can be triggered by local attackers.
The technical implementation of this vulnerability follows a well-established pattern of stack-based buffer overflow where a maliciously crafted input of exactly 512 bytes can overwrite adjacent memory locations. When users paste this oversized string into the File Naming parameter and subsequently click the Preview button, the application's processing routine attempts to copy the input data without proper bounds checking. This allows the buffer to overflow and corrupt the stack memory, leading to unpredictable application behavior and ultimately resulting in a crash. The vulnerability is particularly concerning because it requires minimal user interaction beyond normal application usage, making it easily exploitable in local attack scenarios.
From an operational perspective, this vulnerability creates a significant denial of service risk for users of jetAudio 8.1.7. The attack vector is straightforward and does not require specialized knowledge or remote access capabilities, making it accessible to any local user with access to the application. The crash occurs during routine video conversion operations, which can disrupt workflow and potentially cause data loss if users are in the middle of conversion processes. The 512-byte threshold suggests the application uses a relatively small buffer for filename handling, likely due to assumptions about typical input lengths that were not validated against malicious inputs. This vulnerability aligns with CWE-121, which describes stack-based buffer overflow conditions, and represents a common weakness in software that fails to implement proper input sanitization.
The impact of this vulnerability extends beyond simple application instability, as it can potentially be leveraged as a stepping stone for more sophisticated attacks. While the current exploit only results in denial of service, buffer overflows of this nature often indicate broader code quality issues that could lead to more severe vulnerabilities such as code execution. Security practitioners should consider this vulnerability in the context of the ATT&CK framework, particularly under the T1203 category for legitimate credentials and T1059 for command and scripting interpreter usage. The vulnerability also highlights the importance of following secure coding practices such as those outlined in the OWASP Top Ten and NIST Secure Coding Guidelines, which emphasize the need for input validation and proper memory management in application development.
Mitigation strategies for CVE-2019-25562 should prioritize immediate software updates from the vendor, as this vulnerability is likely patched in newer versions of jetAudio. System administrators should implement application whitelisting policies to restrict execution of vulnerable versions and monitor for unauthorized modifications to the application. Users should be educated about the risks of pasting unknown or untrusted data into application interfaces, particularly in fields that handle file naming or path specifications. Additionally, network segmentation and privilege separation can help limit the potential impact of successful exploitation attempts, while regular security assessments can help identify similar vulnerabilities in other multimedia applications. The vulnerability serves as a reminder of the critical importance of input validation in all software components, especially those handling user-provided data in multimedia processing environments where buffer overflows are particularly common.
