The vulnerability identified as CVE-2026-30982 affects iccDEV, a library and toolset used for handling ICC color management profiles. Specifically, the issue is a heap-based buffer overflow caused by an out-of-bounds read in the function CIccPcsXform::pushXYZConvert(). This function is responsible for converting color data in the ICC profile processing pipeline. Prior to version 2.3.1.5, the function does not properly validate input bounds, leading to reading beyond allocated heap memory. This can cause the application using the library to crash (denial of service) and potentially leak sensitive memory contents, which could include confidential data. The vulnerability requires local access and user interaction, meaning an attacker must have some level of access to the system and trigger the vulnerable function. No privileges are required, which lowers the barrier to exploitation. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H) reflects local attack vector, low complexity, no privileges, user interaction required, unchanged scope, low confidentiality impact, no integrity impact, and high availability impact. The vulnerability is classified under CWE-122 (heap-based buffer overflow), CWE-125 (out-of-bounds read), and CWE-129 (improper validation of array index). No public exploits have been reported yet, but the risk of denial of service and information leakage warrants prompt remediation. The fix is included in iccDEV version 2.3.1.5.

This vulnerability primarily impacts the availability and confidentiality of systems using vulnerable versions of iccDEV. A successful exploit can cause application crashes, leading to denial of service in environments relying on ICC profile processing, such as graphic design, printing, and color management workflows. Additionally, the out-of-bounds read may leak portions of heap memory, potentially exposing sensitive data to local attackers. Although exploitation requires local access and user interaction, the lack of required privileges means that any user on the system could trigger the vulnerability, increasing risk in multi-user or shared environments. Organizations with automated or batch processing of ICC profiles may experience service interruptions. The confidentiality impact is limited but non-negligible, especially if sensitive data resides in memory near the overflow. No integrity impact has been identified. Overall, the vulnerability could disrupt critical color management operations and expose memory contents, affecting operational continuity and data privacy.

To mitigate this vulnerability, organizations should upgrade iccDEV to version 2.3.1.5 or later, where the issue is fixed. If immediate upgrade is not feasible, restrict local user access to systems running vulnerable iccDEV versions to trusted personnel only. Implement strict user privilege separation and limit user interaction with applications that process ICC profiles. Employ application whitelisting and monitoring to detect abnormal crashes or memory leaks associated with the vulnerable function. Conduct code audits and testing of custom software integrating iccDEV to ensure input validation is robust. Additionally, consider sandboxing or isolating ICC profile processing tasks to contain potential crashes and memory exposure. Regularly review and update software dependencies to minimize exposure to known vulnerabilities. Finally, maintain comprehensive logging to detect exploitation attempts and facilitate incident response.
