This vulnerability allows for undefined behavior in the iccDEV library, which is used for manipulating ICC color management profiles. Specifically, versions prior to 2.3.1.2 are impacted by this issue, where the function `CIccTagCurve::CIccTagCurve()` may lead to unexpected application behavior. The severity of this vulnerability is classified as high, with a CVSS score of 7.1. This level of severity indicates the potential for significant risk to systems using affected versions of the library.
Risk to organizations includes potential application crashes and data integrity issues when processing ICC profiles, which could disrupt operations and lead to data loss. Given the nature of the vulnerability and its impact on integrity and availability, organizations should prioritize patching immediately. The patched version, 2.3.1.2, is available and contains necessary fixes to mitigate these risks.
Currently, there are no known workarounds for this vulnerability, and it has not yet been exploited in the wild. Organizations utilizing versions prior to 2.3.1.2 should act promptly to update their systems to avoid potential exploitation in future attacks.
In summary, the urgency for remediation is critical. Organizations relying on the iccDEV library must ensure they are using the latest version to protect against this vulnerability.
Vulnerability Details
The iccDEV library provides essential tools for the interaction and manipulation of ICC color management profiles. Versions before 2.3.1.2 exhibit undefined behavior in the constructor `CIccTagCurve::CIccTagCurve()`, which can lead to stability issues and application crashes. The CVSS score of 7.1 signifies a high severity level, indicating that this vulnerability poses a significant risk due to its potential for exploitation over a network with low complexity.
The vulnerability falls under the Common Weakness Enumeration (CWE) categories CWE-20 (Improper Input Validation) and CWE-758 (Reliance on Undefined Behavior). These classifications highlight the importance of validating inputs and understanding the implications of undefined behavior in software development.
This vulnerability was published on January 7, 2026, and affects all versions prior to the vendor-patched version 2.3.1.2.
Technical Analysis
The root cause of this vulnerability lies in the undefined behavior triggered by the function `CIccTagCurve::CIccTagCurve()`. The attack vector is network-based, requiring that an attacker has the ability to send crafted ICC profiles to the application using iccDEV. The attack complexity is low, with no special privileges required, and user interaction is necessary to process the malformed ICC profile.
The impacts of this vulnerability are multifaceted. While confidentiality is not directly affected, the integrity of the application may be compromised, leading to incorrect processing of color profiles. Furthermore, the availability of the application can be severely impacted due to potential crashes resulting from processing invalid data.
Risk & Impact Analysis
Organizations using the iccDEV library should assess their risk exposure regarding this vulnerability. The potential for instability in applications that rely on ICC color profiles could disrupt workflows and lead to significant operational challenges. Given that the attack complexity is low and requires user interaction to exploit, the risk of successful exploitation increases in environments where user input is not adequately validated.
The urgency for organizations to remediate this issue is high, given the high CVSS score of 7.1, which indicates a significant risk to both integrity and availability. Organizations should prioritize patching to version 2.3.1.2 immediately to mitigate these risks.
