CVE-2019-25558 Overview
CVE-2019-25558 is a local denial of service vulnerability in Pixarra Selfie Studio version 2.17. The flaw resides in the Resize Image function, where the application fails to validate the length of user-supplied input in the New Width and New Height fields. An attacker with local access can paste an excessively long string into either field, triggering an out-of-bounds write [CWE-787] that crashes the application. The vulnerability is classified as a buffer overflow leading to denial of service.
Critical Impact
Local attackers can crash Pixarra Selfie Studio 2.17 by submitting an oversized buffer to the Resize Image dialog, causing loss of availability for the running application instance.
Affected Products
- Pixarra Selfie Studio 2.17
- Windows installations running the affected build
- Systems where the Resize Image dialog is accessible to local users

Technical Details for CVE-2019-25558
Vulnerability Analysis
The defect is an out-of-bounds write [CWE-787] triggered through the Resize Image dialog in Pixarra Selfie Studio 2.17. The application accepts numeric input for the New Width and New Height fields but does not enforce a maximum input length. When a user pastes a very long string into either field, the application copies the input into a fixed-size buffer without bounds checking. The resulting memory corruption causes the process to terminate unexpectedly.
The vulnerability requires local access and user interaction with the affected dialog. It does not result in code execution based on available advisory data, and confidentiality and integrity are not impacted. The outcome is limited to a process crash and loss of any unsaved work within the application session.
Root Cause
The root cause is missing input length validation in the Resize Image handler. The function reads operator-supplied text from the dimension fields directly into a stack or heap buffer of insufficient size. Without a bounds check or safe string copy routine, oversized input writes past the allocated region.
Attack Vector
Exploitation requires local access to a workstation running Selfie Studio 2.17 and interaction with the Resize Image dialog. The attacker pastes an attacker-controlled long string into the New Width or New Height field and submits the dialog. The application crashes immediately upon processing the malformed input. Remote exploitation is not described in the advisory.
A proof of concept is published in Exploit-DB entry 46842. See the Exploit-DB #46842 entry for the reproduction steps.
Detection Methods for CVE-2019-25558
Indicators of Compromise
- Unexpected termination of the Selfie Studio.exe process on hosts running version 2.17
- Windows Application or Error Reporting events referencing a faulting module within the Selfie Studio install directory
- WER crash dumps containing oversized string data in the faulting thread's stack
Detection Strategies
- Inventory endpoints for Pixarra Selfie Studio 2.17 installations using software asset management telemetry
- Monitor Windows Event Log IDs 1000 and 1001 for repeated Selfie Studio crash events that may indicate exploitation attempts
- Correlate process termination events with interactive user sessions to identify localized abuse
Monitoring Recommendations
- Collect endpoint telemetry for application crash events and forward to a centralized log platform for retention
- Alert on multiple Selfie Studio crashes from the same host within a short window
- Review user activity on shared or kiosk systems where untrusted users may have access to the application
How to Mitigate CVE-2019-25558
Immediate Actions Required
- Identify all endpoints running Pixarra Selfie Studio 2.17 and restrict use until a patched version is confirmed
- Limit interactive access to systems where the application is installed, particularly shared or multi-user workstations
- Check the Pixarra official website for vendor updates addressing the Resize Image flaw
Patch Information
No vendor advisory or patched version is referenced in the available data. Consult the Vulncheck advisory on Selfie Studio for the latest remediation status and verify with the vendor before deployment.
Workarounds
- Avoid pasting unverified content into the New Width or New Height fields of the Resize Image dialog
- Replace Selfie Studio 2.17 with an alternative image editor on sensitive workstations until a fix is available
- Apply application control policies to prevent execution of the vulnerable build on managed endpoints
