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 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); }
