9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

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 9191 of biosig.c on the current master branch (35a819fa), when the Tag is 65:

            else if (tag==65)     //0x41: patient event
            {
                // event table

                curPos += ifread(buf,1,len,hdr);
