CVE-2026-24403 in iccDEV
Summary
by MITRE • 01/24/2026
iccDEV provides libraries and tools for interacting with, manipulating, and applying ICC color management profiles. In versions 2.3.1.1 and below, an integer overflow vulnerability exists in icValidateStatus CIccProfile::CheckHeader() when user-controllable input is incorporated into profile data unsafely. Tampering with tag tables, offsets, or size fields can trigger parsing errors, memory corruption, or DoS, potentially enabling arbitrary Code Execution or bypassing application logic. This issue has been fixed in version 2.3.1.2.

The vulnerability identified as CVE-2026-24403 resides within the iccDEV color management library ecosystem, specifically affecting versions 2.3.1.1 and earlier. This library serves as a critical component for handling ICC color profiles across various applications, making it a prime target for attackers seeking to exploit weaknesses in color management systems. The integer overflow vulnerability manifests within the icValidateStatus function of the CIccProfile::CheckHeader() method, where user-controllable input data is processed without adequate validation mechanisms. This flaw represents a classic example of improper input validation that can lead to severe security implications throughout the software stack.
The technical exploitation of this vulnerability occurs when malicious actors manipulate tag tables, offsets, or size fields within ICC profile data structures. These modifications trigger an integer overflow condition during the parsing process, which can result in memory corruption and unpredictable application behavior. The vulnerability's classification aligns with CWE-190, which specifically addresses integer overflow conditions, and demonstrates how such flaws can be leveraged to bypass normal application logic flow. When the integer overflow occurs during header validation, it creates opportunities for attackers to craft specially malformed ICC profiles that can cause buffer overflows, memory corruption, or denial of service conditions that may ultimately lead to arbitrary code execution.
The operational impact of this vulnerability extends beyond simple denial of service scenarios, as it can potentially enable attackers to execute arbitrary code within the context of applications that utilize the iccDEV library. This presents a significant risk to color management workflows in environments where ICC profiles are processed, including graphic design applications, printing systems, and digital imaging software. The vulnerability affects not only the immediate application but can potentially compromise the entire color management pipeline, as ICC profiles are often processed in untrusted environments where attackers might inject malicious data. This weakness creates opportunities for attackers to escalate privileges or bypass security controls that depend on proper color profile validation.
Mitigation strategies for this vulnerability require immediate deployment of version 2.3.1.2, which includes fixed implementations of the header validation logic that properly handle integer overflow conditions. Organizations should implement comprehensive input validation procedures for all ICC profile data, including signature verification, size checking, and boundary validation before processing. The fix addresses the root cause by ensuring that all user-controllable inputs are properly validated and that integer operations are protected against overflow conditions. Security teams should also consider implementing network-level filtering to prevent the processing of untrusted ICC profiles where possible, as recommended in the ATT&CK framework's defense-in-depth strategies for preventing code execution vulnerabilities. Additionally, regular security assessments should verify that all applications utilizing iccDEV libraries have been updated to the patched versions to prevent exploitation attempts targeting this specific integer overflow condition.
