GHSA-5VJV-CQM3-G9M6

Vulnerability from github – Published: 2025-08-25 15:32 – Updated: 2025-11-03 21:34

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 8824 of biosig.c on the current master branch (35a819fa), when the Tag is 11:

            else if (tag==11)    //0x0B
            {
                // Fs
                if (len>6) fprintf(stderr,"Warning MFER tag11 incorrect length %i>6\n",len);
                double  fval;
                curPos += ifread(buf,1,len,hdr);

Severity ?

9.8 (Critical)
