CVE-2025-54488
"The Biosig Project libbiosig Stack-Based Buffer Overflow"
Description

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 8850 of biosig.c on the current master branch (35a819fa), when the Tag is 13: else if (tag==13) { if (len>8) fprintf(stderr,"Warning MFER tag13 incorrect length %i>8\n",len); curPos += ifread(&buf,1,len,hdr);
