CVE-2026-30979 Overview
CVE-2026-30979 is a heap-based buffer overflow vulnerability affecting iccDEV, a widely-used library and toolset for working with ICC color management profiles. The vulnerability exists in the CIccCalculatorFunc::InitSelectOp() function, where improper bounds checking during memory operations can lead to heap corruption when processing maliciously crafted ICC profile data. Successful exploitation requires local user interaction but can result in memory corruption, application crashes, or potentially arbitrary code execution.
Critical Impact
This heap-based buffer overflow vulnerability can be triggered through local user interaction, potentially allowing attackers to corrupt memory, crash applications, or achieve code execution in the context of the vulnerable application.
Affected Products
- iccDEV versions prior to 2.3.1.5

Technical Details for CVE-2026-30979
Vulnerability Analysis
This vulnerability is classified as CWE-120 (Buffer Copy without Checking Size of Input), a classic heap-based buffer overflow condition. The flaw resides in the CIccCalculatorFunc::InitSelectOp() function within the iccDEV library. When processing certain ICC profile data, the function fails to properly validate input boundaries before copying data to heap-allocated buffers, allowing an attacker to write beyond allocated memory regions.
The attack requires local access and some form of user interaction, such as opening a maliciously crafted ICC profile file. Once triggered, the overflow can corrupt adjacent heap memory, potentially overwriting function pointers or other critical data structures. This could lead to denial of service through application crashes, or in more sophisticated attacks, arbitrary code execution.
Root Cause
The root cause stems from insufficient bounds checking in the CIccCalculatorFunc::InitSelectOp() function. When initializing select operations for ICC profile calculator functions, the code fails to properly validate the size of input data against the allocated buffer capacity. This classic buffer overflow pattern (CWE-120) allows data to overflow the heap buffer boundaries when processing specially crafted profile data.
Attack Vector
The attack vector is local, requiring an attacker to deliver a malicious ICC profile to the victim system. The exploitation scenario typically involves:
- An attacker crafts a malicious ICC color profile containing specially structured data designed to trigger the overflow
- The victim opens or processes the malicious profile using an application that relies on the vulnerable iccDEV library
- When CIccCalculatorFunc::InitSelectOp() processes the malformed data, it writes beyond allocated heap buffer boundaries
- The resulting heap corruption can cause immediate crashes or be leveraged for more advanced exploitation techniques
The vulnerability can be exploited through any application workflow that involves parsing ICC profiles, including image editing software, print management systems, or color calibration tools that utilize iccDEV.
Detection Methods for CVE-2026-30979
Indicators of Compromise
- Unexpected crashes in applications using iccDEV libraries when processing ICC profile files
- Memory corruption errors or segmentation faults in processes handling color management
- Presence of unusually large or malformed ICC profile files (.icc or .icm extensions)
- Heap corruption indicators in application logs or crash dumps
Detection Strategies
- Monitor for unexpected application crashes or memory access violations in software utilizing iccDEV
- Implement file integrity monitoring for ICC profile directories
- Deploy endpoint detection solutions capable of identifying heap spray and buffer overflow exploitation techniques
- Audit software inventory to identify applications using iccDEV versions prior to 2.3.1.5
Monitoring Recommendations
- Enable crash reporting and analyze application crash dumps for heap corruption patterns
- Monitor process behavior for suspicious memory allocation patterns during ICC profile processing
- Implement runtime application self-protection (RASP) for applications processing untrusted ICC profiles
- Configure security information and event management (SIEM) rules to correlate application crashes with recent file access events
How to Mitigate CVE-2026-30979
Immediate Actions Required
- Upgrade iccDEV to version 2.3.1.5 or later immediately
- Identify all applications in your environment that depend on iccDEV libraries
- Restrict processing of ICC profiles from untrusted sources until patching is complete
- Apply defense-in-depth measures such as ASLR and DEP to reduce exploitation impact
Patch Information
The International Color Consortium has addressed this vulnerability in iccDEV version 2.3.1.5. The patch implements proper bounds checking in the CIccCalculatorFunc::InitSelectOp() function to prevent heap buffer overflows during ICC profile processing.
Patch Resources:
For additional technical details, refer to GitHub Issue #617.
Workarounds
- Implement input validation to reject ICC profiles exceeding expected size thresholds
- Sandbox applications that process ICC profiles from untrusted sources
- Use application-level controls to disable or limit ICC profile processing functionality where not required
- Deploy exploit mitigation technologies (ASLR, DEP, CFI) to reduce the likelihood of successful exploitation
