The vulnerability identified as CVE-2026-24411 affects the iccDEV library, a toolset used for handling ICC color management profiles. Specifically, the issue lies in the CIccTagXmlSegmentedCurve::ToXml() function, where improper input validation leads to undefined behavior when user-controlled data is incorporated into ICC profiles or related structured binary blobs. ICC profiles are widely used in color management workflows to ensure consistent color reproduction across devices. The flaw can be triggered by processing maliciously crafted ICC profiles, which can cause denial of service by crashing the application, manipulation of data, bypassing of application logic, or even remote code execution under certain conditions. The vulnerability does not require privileges but does require user interaction, such as opening or processing a crafted profile. The root causes relate to CWE-20 (Improper Input Validation), CWE-476 (NULL Pointer Dereference), CWE-690 (Unchecked Return Value to NULL Pointer Dereference), and CWE-758 (Undefined Behavior). The issue has been addressed in iccDEV version 2.3.1.2, which corrects the unsafe handling of input data. No public exploits have been reported yet, but the potential impact is significant given the ability to execute code or disrupt services. The vulnerability is scored 7.1 on the CVSS 3.1 scale, reflecting high severity with network attack vector, low attack complexity, no privileges required, but user interaction needed, and impacts integrity and availability.

For European organizations, the impact of CVE-2026-24411 can be substantial, particularly in industries relying heavily on color management such as printing, graphic design, photography, publishing, and manufacturing sectors that use color profiling for quality control. Exploitation could lead to denial of service, disrupting critical workflows and causing operational downtime. Data manipulation or bypassing application logic could result in incorrect color profiles being applied, degrading product quality or causing reputational damage. In worst cases, remote code execution could allow attackers to gain footholds within enterprise networks, potentially leading to broader compromise. Given the network attack vector and no privilege requirements, attackers could exploit this vulnerability remotely if users process malicious ICC profiles, for example, via email attachments or downloads. This risk is heightened in environments where ICC profiles are shared or imported from external sources without strict validation. The lack of known exploits currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time.

European organizations should immediately upgrade all iccDEV deployments to version 2.3.1.2 or later to remediate this vulnerability. Additionally, implement strict validation and sanitization of ICC profiles before processing, especially those obtained from untrusted or external sources. Employ application whitelisting or sandboxing techniques to isolate processes handling ICC profiles, limiting potential damage from exploitation. Integrate security scanning into workflows that ingest ICC profiles to detect malformed or suspicious files. Educate users about the risks of opening untrusted ICC profiles, particularly via email or downloads. Monitor systems for unusual crashes or behavior that could indicate exploitation attempts. Where possible, restrict network exposure of services that process ICC profiles to trusted internal networks. Finally, maintain up-to-date threat intelligence to respond promptly if exploits emerge in the wild.
