CVE-2026-25634
📋 TL;DR
This CVE describes a buffer overlap vulnerability in iccDEV's CIccTagMultiProcessElement::Apply() function where SrcPixel and DestPixel stack buffers overlap, potentially allowing memory corruption. This affects applications using iccDEV libraries for ICC color profile processing prior to version 2.3.1.4. Attackers could exploit this to execute arbitrary code or cause denial of service.
💻 Affected Systems
- iccDEV library and any software using iccDEV for ICC color profile processing
📦 What is this software?
Iccdev by Color
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, or ransomware deployment.
Likely Case
Application crash or denial of service due to memory corruption, potentially allowing limited information disclosure.
If Mitigated
Application instability or crashes without code execution if memory protections are enabled.
🎯 Exploit Status
Exploitation requires crafting malicious ICC profiles and getting them processed by vulnerable software. No public exploits are currently known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.3.1.4
Vendor Advisory: https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-35rg-jcmp-583h
Restart Required: Yes
Instructions:
1. Identify applications using iccDEV. 2. Update iccDEV to version 2.3.1.4 or later. 3. Recompile applications if using iccDEV as a library. 4. Restart affected applications/services.
🔧 Temporary Workarounds
Input validation for ICC profiles
allImplement strict validation and sanitization of ICC profile inputs before processing.
Memory protection controls
allEnable ASLR, DEP, and other memory protection mechanisms to reduce exploit success.
🧯 If You Can't Patch
- Restrict processing of untrusted ICC profiles to isolated environments
- Implement network segmentation to limit access to vulnerable systems
🔍 How to Verify
Check if Vulnerable:
Check if applications link to or use iccDEV libraries version <2.3.1.4. Review application dependencies and version information.Check Version:
For Linux: `ldd /path/to/application | grep icc` or check package manager. For compiled applications: check build configuration.Verify Fix Applied:
Verify iccDEV version is 2.3.1.4 or later using package manager or version check commands. Test with known safe ICC profiles.📡 Detection & Monitoring
Log Indicators:
- Application crashes with segmentation faults or memory access violations when processing ICC profiles
- Unexpected process termination in color management applications
Network Indicators:
- Unusual uploads of ICC profile files to web applications
- Network traffic containing ICC profile data to vulnerable endpoints
SIEM Query:
Process:Termination AND (ProcessName:contains "color" OR ProcessName:contains "icc") AND ExitCode:0xC0000005🔗 References
