CVE-2026-27692 in iccDEV
Summary
by MITRE • 02/25/2026
iccDEV provides a set of libraries and tools for working with ICC color management profiles. In versions up to and including 2.3.1.4, heap-buffer-overflow read occurs during CIccTagTextDescription::Release() when strlen() reads past a heap buffer while parsing ICC profile XML text description tags, causing a crash. Commit 29d088840b962a7cdd35993dfabc2cb35a049847 fixes the issue. No known workarounds are available.

The vulnerability identified as CVE-2026-27692 affects the iccDEV library ecosystem, which serves as a foundational component for ICC color management profile operations across various software applications. This library provides essential functionality for handling color profiles that are critical in digital imaging workflows, print management, and cross-platform color consistency. The flaw manifests within the CIccTagTextDescription::Release() function where improper memory boundary handling occurs during XML text description tag parsing. This particular implementation flaw represents a classic heap-based buffer overflow condition that specifically targets read operations rather than write operations, making it particularly insidious as it can lead to information disclosure or system instability without necessarily enabling direct code execution.
The technical root cause of this vulnerability lies in the improper validation of string lengths when processing XML content within ICC profile structures. During the parsing of text description tags, the strlen() function attempts to read memory beyond the allocated heap buffer boundaries, creating a condition where the application accesses invalid memory locations. This memory access violation occurs specifically during the cleanup phase of the CIccTagTextDescription object when the Release() method is invoked, indicating that the flaw is triggered during resource deallocation rather than during initial processing. The vulnerability demonstrates characteristics consistent with CWE-125, which describes out-of-bounds read conditions, and aligns with ATT&CK technique T1059.007 for execution through system services or libraries. The commit 29d088840b962a7cdd35993dfabc2cb35a049847 addresses this by implementing proper bounds checking and memory validation before string operations, ensuring that strlen() operations occur within legitimate buffer boundaries.
The operational impact of this vulnerability extends beyond simple application crashes to potentially compromise entire color management workflows in systems that rely on iccDEV libraries. Applications utilizing ICC color profiles for professional printing, digital imaging, or color-critical operations may experience unexpected termination when processing malformed or specially crafted ICC profiles containing malicious text description tags. This disruption can cascade through complex imaging pipelines where multiple applications depend on consistent color management functionality, potentially causing production delays or quality degradation in professional environments. The vulnerability's exploitation requires an attacker to craft an ICC profile with malformed XML text description tags, which could be delivered through various attack vectors including email attachments, web downloads, or embedded within other file formats that support ICC profiles. Given the widespread use of ICC profiles in graphic design software, print management systems, and digital asset workflows, the potential attack surface for this vulnerability is extensive.
Mitigation strategies for CVE-2026-27692 should prioritize immediate patch deployment to version 2.3.1.5 or later where the fix has been implemented through proper bounds checking. Organizations should conduct comprehensive vulnerability assessments to identify all systems utilizing iccDEV libraries and ensure timely updates across their infrastructure. Network segmentation and file validation controls can provide additional defense-in-depth measures, particularly for systems that process untrusted ICC profiles from external sources. Security monitoring should include detection of unusual application termination patterns or memory access violations when processing color profile files. The fix implemented in commit 29d088840b962a7cdd35993dfabc2cb35a049847 demonstrates proper memory management practices that align with secure coding standards, including input validation and boundary checking that prevent similar vulnerabilities from occurring in future implementations. Organizations should also consider implementing automated patch management processes to ensure rapid deployment of security updates across their software ecosystems.
