CVE-2026-24412 in iccDEV
Summary
by MITRE • 01/24/2026
iccDEV provides libraries and tools for interacting with, manipulating, and applying ICC color management profiles. Versions 2.3.1.1 and below have aHeap Buffer Overflow vulnerability in the CIccTagXmlSegmentedCurve::ToXml() function. This occurs when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs. Successful exploitation may allow an attacker to perform DoS, manipulate data, bypass application logic and Code Execution. This issue has been fixed in version 2.3.1.2.

The vulnerability CVE-2026-24412 affects iccDEV, a software library and toolkit designed for ICC color management profile manipulation and interaction. This library serves as a critical component in color management systems across various applications including graphic design software, printing systems, and digital imaging platforms. The affected versions 2.3.1.1 and earlier contain a heap buffer overflow vulnerability within the CIccTagXmlSegmentedCurve::ToXml() function, which represents a significant security risk for systems relying on proper color management protocols. The flaw manifests when user-controllable input data is processed through the library's XML conversion routines without adequate bounds checking or input validation mechanisms.
The technical implementation of this vulnerability stems from improper memory management within the ToXml() function that handles segmented curve data structures in ICC profiles. When the library processes malformed or maliciously crafted ICC profile data containing user-controllable input, the function fails to validate buffer boundaries during XML serialization operations. This oversight creates a classic heap buffer overflow condition where adjacent memory locations can be overwritten, potentially leading to arbitrary code execution or system instability. The vulnerability specifically targets the handling of structured binary data within ICC profiles, making it particularly dangerous for applications that process color profile information from untrusted sources. According to CWE guidelines, this represents a CWE-121 heap-based buffer overflow vulnerability, classified under the broader category of memory safety issues that compromise program integrity and execution flow.
The operational impact of this vulnerability extends beyond simple denial of service scenarios, presenting multiple attack vectors that could compromise system security. An attacker exploiting this vulnerability could potentially achieve code execution within the context of the affected application, allowing for privilege escalation and persistent access to compromised systems. The vulnerability's potential for data manipulation means that color profile data could be altered in ways that affect print output, image rendering, or color correction processes, creating both security and functional risks. Additionally, the bypass capabilities associated with this flaw could allow attackers to circumvent application logic controls, potentially undermining security policies and access controls within color management workflows. This vulnerability particularly affects applications that process external color profiles, such as photo editing software, print management systems, and digital asset management platforms where users might inadvertently or maliciously introduce compromised ICC profiles into the processing pipeline.
Mitigation strategies for CVE-2026-24412 should prioritize immediate deployment of the patched version 2.3.1.2, which addresses the heap buffer overflow through proper bounds checking and input validation mechanisms. Organizations should implement comprehensive input sanitization procedures for all ICC profile data processing, particularly when handling external or user-provided color profiles. Network segmentation and application whitelisting can help limit the potential impact of exploitation attempts by restricting access to vulnerable applications. Security monitoring should include detection of unusual file processing patterns or memory allocation anomalies that might indicate exploitation attempts. The ATT&CK framework categorizes this vulnerability under T1059 command and control communication and T1068 local privilege escalation techniques, highlighting the need for defensive measures that address both initial compromise and post-exploitation activities. Regular security assessments and vulnerability scanning should be implemented to identify any remaining instances of affected software versions within the organization's infrastructure. System administrators should also consider implementing automated patch management processes to ensure rapid deployment of security updates across all affected systems and applications.
