Summary
by MITRE • 03/21/2026
Selfie Studio 2.17 contains a denial of service vulnerability in the Resize Image function that allows local attackers to crash the application by supplying an excessively long buffer. Attackers can paste a large string of characters into the New Width or New Height field to trigger a buffer overflow that crashes the application.

The vulnerability identified as CVE-2019-25558 resides within Selfie Studio version 2.17, specifically within its Resize Image functionality. This represents a classic buffer overflow condition that manifests when the application fails to properly validate input parameters supplied by users. The flaw occurs in the image processing pipeline where the software does not implement adequate bounds checking for dimensional inputs, creating a scenario where maliciously crafted data can overwhelm the allocated memory buffers. The vulnerability is particularly concerning as it operates at the application level and requires no elevated privileges to exploit, making it accessible to any local user with access to the software interface.
The technical implementation of this vulnerability stems from improper input validation within the Resize Image component of the application. When users input values into the New Width or New Height fields, the software processes these parameters without sufficient sanitization or length constraints. This allows attackers to submit extremely long strings of characters that exceed the expected buffer capacity, causing the application to crash during memory allocation or data processing. The buffer overflow occurs because the application's internal memory management does not account for arbitrarily large input values, leading to memory corruption that terminates the process. This type of vulnerability aligns with CWE-121, which describes stack-based buffer overflow conditions, and represents a fundamental flaw in input handling and memory management practices.
From an operational perspective, this denial of service vulnerability significantly impacts the usability and reliability of Selfie Studio. Local attackers can easily disrupt the application's normal operation by simply pasting a large string into the input fields, causing immediate application termination. The impact extends beyond simple disruption as it can potentially lead to data loss if users are in the middle of image processing operations. The vulnerability demonstrates a lack of robust error handling and input validation that should be standard practice in software development. Organizations relying on this application for image processing tasks face potential operational interruptions that could affect productivity and user experience. The attack vector is particularly dangerous because it requires minimal technical skill to execute, making it a viable threat for any local user with access to the system.
Mitigation strategies for CVE-2019-25558 should focus on implementing comprehensive input validation and boundary checking within the Resize Image functionality. The most effective immediate solution involves adding strict length limitations to the New Width and New Height fields, ensuring that input values fall within reasonable ranges for image dimensions. Software developers should implement proper memory management techniques including dynamic buffer allocation with size validation, and employ defensive programming practices such as input sanitization and bounds checking. The application should also incorporate robust error handling mechanisms that gracefully manage invalid inputs rather than allowing crashes to occur. Security patches should be developed to address the underlying buffer overflow condition by ensuring that all user-supplied data is validated before processing. Additionally, implementing application sandboxing or containerization can provide additional protection layers that limit the impact of such vulnerabilities. This vulnerability highlights the importance of adhering to secure coding practices and following established security frameworks that address common software flaws. The issue also aligns with ATT&CK technique T1499, which covers network denial of service attacks, though in this case it operates within the local application context rather than network-based attacks. Organizations should prioritize updating to patched versions of Selfie Studio and implementing input validation controls as recommended by the software vendor to prevent exploitation of this vulnerability.
