CVE-2026-21686 Details
Description
iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of International Color Consortium (ICC) color management profiles. Versions prior to 2.3.1.2 have Undefined Behavior in `CIccTagLutAtoB::Validate()`. This vulnerability affects users of the iccDEV library who process ICC color profiles. Version 2.3.1.2 contains a patch. No known workarounds are available.
A vulnerability causing undefined behavior has been identified in the iccDEV library, specifically in the CIccTagLutAtoB::Validate() function. This issue, which leads to a heap-buffer-overflow, affects versions of iccDEV prior to 2.3.1.2. The vulnerability arises when the function processes ICC color profiles, as it incorrectly handles channel counts, allowing for potential memory corruption.
