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 a NULL pointer dereference vulnerability. This vulnerability affects users of the iccDEV library who process ICC color profiles. Version 2.3.1.2 contains a patch.

A NULL pointer dereference vulnerability has been identified in the iccDEV library, specifically in versions prior to 2.3.1.2. This vulnerability occurs in the 'CIccProfile::CheckTagTypes()' function, where the code improperly handles NULL pointers, leading to potential crashes. The issue was discovered through fuzz testing with LibFuzzer, which revealed that certain malformed ICC color profiles could trigger the vulnerability.
