An attacker can provide a malicious file to trigger this vulnerability.This vulnerability manifests on line 8751 of biosig.c on the current master branch (35a819fa), when the Tag is 4:
else if (tag==4) {
// SPR
if (len>4) fprintf(stderr,"Warning MFER tag4 incorrect length %i>4\n",len);
curPos += ifread(buf,1,len,hdr);
