CVE-2026-25585 is a vulnerability identified in the InternationalColorConsortium's iccDEV library, which is widely used for handling ICC color management profiles. The issue exists in versions prior to 2.3.1.3, specifically in the IccCmm.cpp file at line 5793, where the software improperly validates array bounds while reading through an index during ICC profile processing. This improper restriction of operations within the bounds of a memory buffer (CWE-119) leads to an out-of-bounds read, which can cause memory disclosure or a segmentation fault by accessing memory beyond the allocated array. The vulnerability is triggered by processing a malformed ICC profile, which can be crafted by an attacker. The CVSS v3.1 score of 7.8 indicates a high severity, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Although no exploits are currently known in the wild, the vulnerability poses a significant risk to systems that process untrusted ICC profiles. The issue has been patched in iccDEV version 2.3.1.3, and users are advised to upgrade to this or later versions to mitigate the risk.

For European organizations, the vulnerability presents a considerable risk, particularly for those in sectors relying heavily on color management and digital imaging workflows, such as printing, publishing, photography, and graphic design. Exploitation could lead to unauthorized disclosure of sensitive memory contents, potentially exposing confidential information processed or stored in memory. Additionally, the segmentation fault could cause denial of service in critical applications, disrupting business operations. Since the attack requires local access and user interaction, the threat is more relevant in environments where users might open or process untrusted ICC profiles, such as email attachments or downloads from external sources. The impact is heightened in organizations that integrate iccDEV into larger software stacks or automated processing pipelines, where a single malformed profile could affect multiple systems. The confidentiality, integrity, and availability of affected systems are all at risk, which could lead to data breaches, operational downtime, and reputational damage.

European organizations should immediately update iccDEV to version 2.3.1.3 or later to ensure the vulnerability is patched. Additionally, implement strict validation and sanitization of ICC profiles before processing, especially those received from untrusted or external sources. Employ application whitelisting and sandboxing techniques to isolate processes handling ICC profiles, limiting the potential impact of exploitation. Educate users about the risks of opening unknown or suspicious files that may contain malicious ICC profiles. Integrate security monitoring to detect abnormal application crashes or memory access violations that could indicate exploitation attempts. For environments where updating iccDEV is not immediately feasible, consider disabling or restricting the processing of ICC profiles in workflows where possible. Regularly review and audit software dependencies to identify and remediate vulnerable versions promptly. Finally, maintain up-to-date backups and incident response plans to mitigate potential denial-of-service impacts.
