An attacker can provide a malicious file to trigger this vulnerability.This vulnerability manifests on line 8759 of biosig.c on the current master branch (35a819fa), when the Tag is 5:

            else if (tag==5)     //0x05: number of channels
            {
                uint16_t oldNS=hdr->NS;
                if (len>4) fprintf(stderr,"Warning MFER tag5 incorrect length %i>4\n",len);
