CVE-2026-24405 is a heap buffer overflow vulnerability identified in the InternationalColorConsortium's iccDEV library, specifically affecting versions earlier than 2.3.1.2. iccDEV is widely used for interacting with and manipulating ICC color management profiles, which are essential for consistent color reproduction across devices and software. The vulnerability exists in the CIccMpeCalculator::Read() function, where user-controllable input embedded within ICC profiles or other structured binary blobs is not properly validated before being processed. This improper input validation (CWE-20) leads to a heap buffer overflow (CWE-122), enabling attackers to overwrite memory beyond allocated buffers. Successful exploitation can cause application crashes (denial of service), unauthorized data manipulation, bypass of application logic, and potentially remote code execution, allowing attackers to execute arbitrary code within the context of the vulnerable application. The CVSS v3.1 base score is 8.8, indicating high severity, with attack vector being network-based, no privileges required, but user interaction is necessary. The scope is unchanged, meaning the vulnerability affects only the vulnerable component. Although no known exploits have been reported in the wild, the potential impact is significant due to the nature of the vulnerability and the critical role of iccDEV in color management workflows. The issue was publicly disclosed on January 24, 2026, and fixed in version 2.3.1.2. Organizations using iccDEV in image processing, printing, or color calibration software should upgrade promptly to mitigate risks.

For European organizations, the impact of CVE-2026-24405 can be substantial, particularly for industries relying on accurate color management such as digital media production, printing, publishing, photography, and manufacturing sectors involving color-critical processes. Exploitation could lead to denial of service, disrupting business operations and workflows dependent on color profile processing. More critically, remote code execution could allow attackers to compromise systems, potentially leading to data breaches, intellectual property theft, or further lateral movement within networks. Given the network attack vector and lack of required privileges, attackers could target exposed services or trick users into opening malicious ICC profiles, increasing the risk of widespread exploitation. The integrity of color data and related application logic could be compromised, affecting product quality and brand reputation. Additionally, disruption in printing and media workflows could have economic consequences. The absence of known exploits currently provides a window for proactive mitigation, but the high CVSS score underscores the urgency for patching.

European organizations should immediately upgrade iccDEV to version 2.3.1.2 or later to remediate this vulnerability. Where immediate patching is not feasible, implement strict input validation and sanitization controls on ICC profile data before processing. Employ network-level protections such as firewalls and intrusion detection/prevention systems to monitor and block suspicious traffic targeting services that utilize iccDEV. Limit user interaction with untrusted ICC profiles by enforcing strict file handling policies and educating users about the risks of opening unsolicited or unknown color profile files. Conduct thorough code audits and integrate fuzz testing for components handling ICC profiles to detect similar vulnerabilities proactively. Additionally, apply application whitelisting and sandboxing techniques to isolate processes using iccDEV, minimizing potential damage from exploitation. Maintain up-to-date backups and incident response plans tailored to address potential exploitation scenarios involving this vulnerability.
