A stack-based buffer overflow vulnerability exists in the MFER parsing functionality of The Biosig Project libbiosig 3.9.0 and Master Branch (35a819fa). A specially crafted MFER file can lead to arbitrary code execution. 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);
