Assimp through 6.0.6 contains a heap out-of-bounds read vulnerability in MD2Importer::InternReadFile that allows attackers to read past the file buffer via an unvalidated stored frameSize header field. Attackers can supply a crafted .md2 file loaded with a non-zero keyframe selected to crash the application or leak adjacent heap memory into the imported mesh.
