CVE-2026-24411 Overview
CVE-2026-24411 is a high-severity vulnerability affecting iccDEV, a library and toolset for interacting with, manipulating, and applying ICC color management profiles. The vulnerability stems from Undefined Behavior in the CIccTagXmlSegmentedCurve::ToXml() function, which occurs when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs.
Critical Impact
Successful exploitation may allow an attacker to perform Denial of Service (DoS), manipulate data, bypass application logic, and potentially achieve Code Execution.
Affected Products
- iccDEV versions 2.3.1.1 and below
- Applications integrating vulnerable iccDEV libraries for ICC color profile processing
- Systems processing untrusted ICC color management profile data

Technical Details for CVE-2026-24411
Vulnerability Analysis
This vulnerability is classified under CWE-20 (Improper Input Validation). The CIccTagXmlSegmentedCurve::ToXml() function in iccDEV fails to properly validate user-controllable input before incorporating it into ICC profile data structures. When processing maliciously crafted ICC profiles or structured binary data, the function exhibits undefined behavior, which can be exploited by attackers to cause various security impacts.
The vulnerability exists in the XML conversion functionality of segmented curve tags within ICC profiles. When the library processes a specially crafted ICC profile containing malformed segmented curve data, the ToXml() method does not adequately validate input boundaries or data integrity before performing operations on the data.
Root Cause
The root cause of CVE-2026-24411 lies in improper input validation within the CIccTagXmlSegmentedCurve::ToXml() function. The function fails to sanitize or validate user-controllable input before processing it, leading to undefined behavior when handling malicious ICC profile data. This lack of input validation allows attackers to inject specially crafted data that causes the application to behave unpredictably.
Attack Vector
The attack vector for this vulnerability is network-based, requiring user interaction (such as opening a malicious file). An attacker can exploit this vulnerability by:
- Crafting a malicious ICC color profile containing specially constructed segmented curve data
- Distributing the malicious profile through various channels (email attachments, web downloads, embedded in images)
- Triggering the vulnerable ToXml() function when a victim application processes the malicious profile
The vulnerability manifests when the iccDEV library parses and converts segmented curve tag data to XML format. The lack of proper input validation allows attackers to supply malformed data that triggers undefined behavior in the parsing logic. For detailed technical information, refer to the GitHub Security Advisory and the issue tracker.
Detection Methods for CVE-2026-24411
Indicators of Compromise
- Unexpected application crashes when processing ICC color profiles
- Abnormal memory consumption patterns in applications using iccDEV libraries
- Crash dumps indicating failures in CIccTagXmlSegmentedCurve::ToXml() or related functions
- Suspicious ICC profile files with malformed segmented curve data structures
Detection Strategies
- Monitor applications using iccDEV for unexpected crashes or exceptions during ICC profile processing
- Implement file integrity monitoring for ICC profiles in processing pipelines
- Deploy application-level logging to capture ICC profile parsing events and failures
- Use SentinelOne Singularity platform to detect anomalous behavior patterns in applications processing color profiles
Monitoring Recommendations
- Enable crash reporting and logging for applications utilizing iccDEV libraries
- Monitor system resources for unusual memory or CPU consumption during ICC profile processing
- Implement network traffic analysis to detect potentially malicious ICC profiles being transferred
- Configure SentinelOne agents to monitor for exploitation patterns associated with ICC profile processing
How to Mitigate CVE-2026-24411
Immediate Actions Required
- Upgrade iccDEV to version 2.3.1.2 or later immediately
- Audit applications and systems for usage of vulnerable iccDEV versions (2.3.1.1 and below)
- Implement input validation for ICC profiles before processing with iccDEV libraries
- Consider restricting ICC profile processing to trusted sources only until patching is complete
Patch Information
The vulnerability has been addressed in iccDEV version 2.3.1.2. The fix is available in the GitHub commit. Organizations should update their iccDEV installations to this version or later to remediate the vulnerability.
Workarounds
- Avoid processing ICC color profiles from untrusted or unknown sources
- Implement strict input validation and sanitization for ICC profile data before passing to iccDEV functions
- Run applications using iccDEV in sandboxed environments to limit potential impact
- Deploy application-level controls to filter and validate ICC profiles before processing
