An attacker can provide a malicious file to trigger this vulnerability.This vulnerability manifests on line 8719 of biosig.c on the current master branch (35a819fa), when the Tag is 0:
if (tag==0) {
if (len!=1) fprintf(stderr,"Warning MFER tag0 incorrect length %i!=1\n",len);
curPos += ifread(buf,1,len,hdr);
