Details

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 8785 of biosig.c on the current master branch (35a819fa), when the Tag is 8:

            else if (tag==8) {
                if (len>2) fprintf(stderr,"Warning MFER tag8 incorrect length %i>2\n",len);
                curPos += ifread(buf,1,len,hdr);
