On January 6, 2026, a high-severity vulnerability was identified in the Color iccDEV library, which provides tools for managing ICC color profiles. The vulnerability, classified as CVE-2026-21507, affects all versions up to 2.3.1 and is characterized by an infinite loop within the CalcProfileID function in IccProfile.cpp. This flaw can lead to significant availability issues, making it critical for organizations to address this vulnerability promptly.
The Common Vulnerability Scoring System (CVSS) score for this vulnerability is 7.5, indicating a high severity level. The availability impact is marked as high, which signifies that successful exploitation can lead to a denial-of-service situation, causing the affected application to become unresponsive. Organizations utilizing iccDEV should prioritize applying the patch available in version 2.3.1.1 to mitigate this risk.
Currently, there are no known exploits for this vulnerability, as indicated by the lack of public proof-of-concept code. However, the nature of the infinite loop means that it could potentially be exploited in a network context with low complexity, requiring no privileges or user interaction. Hence, the urgency for organizations to implement the patch is underscored.
Organizations should prioritize patching immediately to ensure the integrity of their systems and prevent any potential denial-of-service attacks that may arise from this vulnerability. The next section will delve into the specifics of the vulnerability.
Vulnerability Details
CVE-2026-21507 involves an infinite loop in the IccProfile.cpp function, CalcProfileID, in versions 2.3.1 and below of the iccDEV library. This vulnerability is categorized under CWE-835, which refers to the 'Infinite Loop' weakness. The vulnerability can be exploited in network contexts with low complexity, requiring no privileges or user interaction.
The CVSS score of 7.5 reflects a high severity level. The attack vector is classified as network-based, meaning that the vulnerability can be exploited remotely. The availability impact is particularly significant, as an attacker could cause the application to hang indefinitely, resulting in a denial-of-service state.
The issue was disclosed on January 6, 2026, and it has been addressed in version 2.3.1.1 of the iccDEV library. Organizations using this library should take immediate action to upgrade to this version to avoid potential service disruptions.
Technical Analysis
The root cause of the vulnerability lies in the CalcProfileID function, where an infinite loop can occur under specific input conditions. This flaw leads to a situation where the function fails to terminate, consuming CPU resources and preventing the application from performing other tasks. The attack vector is network-based, allowing remote exploitation with minimal effort.
The attack complexity is low, and no special privileges or user interaction are needed to exploit this vulnerability. This combination raises the potential risk to organizations, especially those leveraging the iccDEV library in production environments.
The impacts on confidentiality and integrity are rated as none, as the vulnerability does not compromise data security; however, the availability impact is high. This means that systems using affected versions of iccDEV could become unavailable, impacting service delivery and user experience.
Risk & Impact Analysis
The real-world risk to organizations using iccDEV is significant, given the nature of the vulnerability. The potential for an infinite loop to lead to denial-of-service conditions means that critical applications depending on this library could face unexpected downtime. This could disrupt business operations, resulting in financial losses and damage to reputation.
With a CVSS score of 7.5, organizations should assess this vulnerability with a high priority. The lack of known exploits does not diminish the urgency for remediation, as the conditions for exploitation are straightforward and can be executed by an attacker with minimal skill.
Organizations should address this vulnerability in their patch cycle to mitigate potential risks. The blast radius is considerable, especially for services reliant on the iccDEV library in a production environment, necessitating immediate action to prevent exploitation.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions of the iccDEV library include all versions prior to 2.3.1.1. Organizations utilizing these versions should upgrade to the fixed version to eliminate the vulnerability.
Mitigation & Remediation
To mitigate this vulnerability, organizations should apply the patch provided in version 2.3.1.1 of the iccDEV library. If immediate patching is not feasible, consider implementing network controls to restrict access to the affected application until the patch can be applied.
For further assistance, organizations can consider engaging in penetration testing services to validate their security posture against such vulnerabilities.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor system logs for unusual CPU usage patterns or application hangs. Additionally, monitoring for network traffic that may indicate attempts to exploit the CalcProfileID function could provide early warnings.
AppSecure Threat Intelligence Insight
