Severity ?
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
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 8759 of biosig.c on the current master branch (35a819fa), when the Tag is 5: else if (tag==5) //0x05: number of channels { uint16_t oldNS=hdr->NS; if (len>4) fprintf(stderr,"Warning MFER tag5 incorrect length %i>4\n",len); curPos += ifread(buf,1,len,hdr);
