CVE-2019-25329
FTP Navigator 8.03 contains a denial of service vulnerability that allows attackers to crash the application by overwriting Structured Exception Handler (SEH) with malicious input.
Does this matter?
Lower severity and a low EPSS score (0.50%). Track it; it rarely justifies an emergency change on its own.
