Lifecycle Timeline
2DescriptionGitHub Advisory
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a heap-buffer-overflow (HBO) in CIccApplyCmmSearch::costFunc() can be triggered via malformed JSON configuration input to the iccApplySearch tool. AddressSanitizer reports an out-of-bounds READ of size 8 originating from CIccApplyCmmSearch::costFunc(CIccSearchVec&) at IccProfLib/IccCmmSearch.cpp:112:5. This issue has been patched in version 2.3.1.6.
AnalysisAI
Heap buffer overflow in iccDEV's CIccApplyCmmSearch::costFunc() function allows local attackers to trigger an out-of-bounds memory read via malformed JSON configuration input to the iccApplySearch tool, resulting in denial of service. The vulnerability affects iccDEV versions prior to 2.3.1.6 and has been patched; no public exploit identified at time of analysis, though the issue is straightforward to trigger with crafted input.

Vulnerability AssessmentAI
| Risk Assessment | CVSS 6.2 (Medium) reflects a local attack vector with low complexity and no authentication requirements, but impact is limited to availability (denial of service via crash). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with local filesystem access crafts a malformed JSON configuration file with out-of-bounds array references and supplies it to the iccApplySearch tool via command-line arguments. The costFunc() method reads beyond allocated heap memory when processing the crafted JSON structure, triggering AddressSanitizer detection and causing the tool to crash. … |
| Remediation | Vendor-released patch: upgrade iccDEV to version 2.3.1.6 or later, which includes the fix merged via GitHub PR #738. … Detailed patch versions, workarounds, and compensating controls in full report. |
