An integer overflow vulnerability exists in the sopen_FAMOS_read functionality of The Biosig Project libbiosig 2.5.0 and Master Branch (ab0ee111). A specially crafted .famos file can lead to an out-of-bounds write which in turn can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.
