CVE-2026-30982: iccDEV Buffer Overflow Vulnerability

CVE-2026-30982 Overview

CVE-2026-30982 is a heap out-of-bounds read vulnerability in iccDEV, a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.5, the vulnerability exists in the CIccPcsXform::pushXYZConvert() function, which can cause application crashes and potentially leak sensitive memory contents when processing maliciously crafted ICC profile data.

Critical Impact

This vulnerability can lead to denial of service through application crashes and potential information disclosure through memory content leakage. Local attackers can exploit this by convincing users to open specially crafted ICC profile files.

Affected Products

• iccDEV versions prior to 2.3.1.5
• Applications and systems integrating vulnerable iccDEV libraries
• Color management workflows utilizing affected library versions

Technical Details for CVE-2026-30982

Vulnerability Analysis

This vulnerability is classified as CWE-122 (Heap-based Buffer Overflow), specifically manifesting as an out-of-bounds read condition. The flaw resides in the CIccPcsXform::pushXYZConvert() function within the iccDEV color management library. When processing ICC profile data, this function fails to properly validate array boundaries before performing read operations, allowing memory access beyond allocated buffer regions.

The local attack vector requires user interaction, as an attacker must convince a victim to open a maliciously crafted ICC profile file. Once processed, the vulnerable function attempts to read memory outside the designated heap buffer, resulting in either application termination or the unintended exposure of adjacent memory contents.

Root Cause

The root cause stems from insufficient bounds checking in the CIccPcsXform::pushXYZConvert() function. The function processes XYZ color space conversion data from ICC profiles without adequately verifying that index values or data sizes remain within allocated buffer boundaries. This oversight allows specially crafted ICC profiles to trigger read operations that access heap memory beyond the intended buffer limits.

Attack Vector

The attack requires local access and user interaction. An attacker would craft a malicious ICC color profile containing manipulated data structures designed to trigger the out-of-bounds read condition. The attack sequence involves:

1. Creating a specially crafted ICC profile with malformed XYZ conversion data
2. Distributing the malicious profile to potential victims
3. Convincing the victim to open or process the malicious ICC profile using an application that utilizes the vulnerable iccDEV library
4. Upon processing, the CIccPcsXform::pushXYZConvert() function reads beyond heap buffer boundaries

The vulnerability mechanism involves improper memory access during ICC profile processing. When the CIccPcsXform::pushXYZConvert() function handles XYZ color space conversion, it can read beyond allocated heap buffer boundaries due to insufficient validation of input data. Technical details and the specific fix can be found in the GitHub Security Advisory GHSA-7ww3-h4w6-x5hf and Pull Request #632.

Detection Methods for CVE-2026-30982

Indicators of Compromise

• Unexpected application crashes when processing ICC color profiles
• Memory access violations or segmentation faults in applications using iccDEV libraries
• Abnormal memory consumption patterns during ICC profile processing
• Error logs indicating heap corruption or invalid memory reads in color management operations

Detection Strategies

• Monitor applications utilizing iccDEV libraries for abnormal crash patterns
• Implement file integrity monitoring for ICC profile files in critical workflows
• Deploy memory sanitization tools (AddressSanitizer, Valgrind) in development and testing environments to detect out-of-bounds access
• Review application logs for heap corruption indicators related to color profile processing

Monitoring Recommendations

• Enable crash reporting and analysis for applications that process ICC profiles
• Implement anomaly detection for unusual ICC profile file characteristics (size, structure)
• Monitor system logs for segmentation fault signals in processes utilizing iccDEV
• Consider deploying endpoint detection solutions capable of identifying memory exploitation attempts

How to Mitigate CVE-2026-30982

Immediate Actions Required

• Upgrade iccDEV to version 2.3.1.5 or later immediately
• Audit systems and applications to identify all instances of vulnerable iccDEV library versions
• Implement input validation for ICC profile files before processing
• Restrict access to ICC profile processing capabilities to trusted users only

Patch Information

The vulnerability has been fixed in iccDEV version 2.3.1.5. The patch addresses the bounds checking deficiency in the CIccPcsXform::pushXYZConvert() function to prevent out-of-bounds heap reads. Organizations should update to the patched version available through the official release. The specific fix implementation can be reviewed in Pull Request #632.

Workarounds

• Disable or restrict ICC profile processing functionality until patching is complete
• Implement application-level sandboxing for processes that handle ICC profiles
• Configure systems to only accept ICC profiles from trusted sources
• Deploy endpoint protection solutions to monitor for exploitation attempts
