CVE-2026-24412
📋 TL;DR
A heap buffer overflow vulnerability in iccDEV's CIccTagXmlSegmentedCurve::ToXml() function allows attackers to execute arbitrary code or cause denial of service by supplying malicious ICC profile data. This affects all users of iccDEV libraries and tools versions 2.3.1.1 and below. The vulnerability is particularly dangerous because it can be triggered through user-controllable input in applications that process ICC profiles.
💻 Affected Systems
- iccDEV libraries and tools
📦 What is this software?
Iccdev by Color
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the application processing the ICC profile, potentially leading to complete system compromise.
Likely Case
Application crash (denial of service) or limited data manipulation, though code execution is possible with crafted exploits.
If Mitigated
Application crash with no data loss if proper input validation and sandboxing are implemented.
🎯 Exploit Status
Exploitation requires crafting malicious ICC profile data, but no authentication is needed if the application processes untrusted profiles. The vulnerability is in a widely used library function.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.3.1.2
Vendor Advisory: https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-6rf4-63j2-cfrf
Restart Required: Yes
Instructions:
1. Identify all applications using iccDEV libraries
2. Update iccDEV to version 2.3.1.2 or later
3. Recompile applications if using static libraries
4. Restart affected applications and services
🔧 Temporary Workarounds
Input Validation for ICC Profiles
allImplement strict validation of ICC profile data before passing to iccDEV functions
# Implement custom validation logic in your application code
# Reject ICC profiles with unexpected sizes or malformed structures
Sandbox ICC Profile Processing
linuxIsolate ICC profile processing in separate containers or sandboxes
# Use Docker containers with limited privileges
# Implement seccomp filters or AppArmor/SELinux policies
🧯 If You Can't Patch
- Implement strict input validation for all ICC profile data before processing
- Isolate applications that process ICC profiles in network segments with limited access
🔍 How to Verify
Check if Vulnerable:
Check if your application links to iccDEV libraries version 2.3.1.1 or earlierCheck Version:
ldd /path/to/application | grep icc or check package manager (apt list --installed | grep iccdev)Verify Fix Applied:
Verify iccDEV version is 2.3.1.2 or later and test with known safe ICC profiles📡 Detection & Monitoring
Log Indicators:
- Application crashes with segmentation faults when processing ICC profiles
- Unexpected memory access errors in application logs
Network Indicators:
- Unusual ICC profile uploads to web applications
- Large or malformed ICC profile transfers
