DescriptionGitHub Advisory

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 heap-buffer-overflow in CIccXmlArrayType::ParseText(). 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.

AnalysisAI

Heap buffer overflow in iccDEV versions before 2.3.1.2 allows remote code execution when processing malicious ICC color profiles, affecting applications that use the library to handle color management data. An attacker can trigger the vulnerability through a crafted profile file requiring only user interaction to open, potentially achieving complete system compromise. …
