CVE-2026-21678
7.8International Color Consortium · iccDEV
A heap-based buffer overflow vulnerability exists in the IccTagXml function of the iccDEV library, potentially allowing arbitrary code execution through improper input validation.
Executive summary
A heap-based buffer overflow in the International Color Consortium iccDEV library (versions prior to 2.3.1.2) poses a significant risk of memory corruption and potential system compromise.
Vulnerability
The vulnerability is a heap-based buffer overflow (CWE-122) triggered within the IccTagXml function due to improper input validation (CWE-20). The CVSS vector indicates that this issue requires local user interaction, but does not require authentication to trigger if a malicious ICC profile is processed.
Business impact
Successful exploitation of this memory corruption vulnerability can lead to a crash or the execution of arbitrary code within the context of the application processing the ICC profile. Given the CVSS score of 7.8, this represents a High severity risk that could result in full loss of confidentiality, integrity, and availability for the affected application or local user session.
Remediation
Immediate Action: Update the iccDEV library to version 2.3.1.2 or later to apply the necessary input validation fixes.
Proactive Monitoring: Review application logs for unusual crashes or error patterns associated with the parsing of ICC color management profiles.
Compensating Controls: Restrict the processing of untrusted or externally sourced ICC color profiles within sensitive applications until the library can be updated.
Exploitation status
Public Exploit Available: Unknown
Analyst recommendation
This vulnerability presents a clear risk to any system utilizing the iccDEV library for color profile management. Administrators should prioritize the update to version 2.3.1.2 across all development and production environments to remediate this heap overflow flaw. Failure to patch may leave systems susceptible to malicious profile injection attacks.
