Description

FTP Voyager 16.2.0 contains a denial of service vulnerability that allows local attackers to crash the application by injecting oversized buffer data into the site profile IP field. Attackers can create a malicious site profile containing 500 bytes of repeated characters and paste it into the IP field to trigger a buffer overflow that crashes the FTP Voyager process.
