HIGH 7.8

DescriptionGitHub Advisory

iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Prior to 2.3.1.4, SrcPixel and DestPixel stack buffers overlap in CIccTagMultiProcessElement::Apply() int IccTagMPE.cpp. This vulnerability is fixed in 2.3.1.4.

AnalysisAI

Stack buffer overlap in iccDEV's color profile processing library prior to version 2.3.1.4 enables local attackers with user interaction to achieve arbitrary code execution through malicious ICC color management profiles. The vulnerability exists in the CIccTagMultiProcessElement::Apply() function where SrcPixel and DestPixel buffers overlap, and public exploit code is currently available. …
