CRITICAL Flexense CVE published 2017-03-06

CVE-2017-6416

CVE-2017-6416 is a critical buffer overflow in Flexense SysGauge 1.5.18's SMTP connection verification logic. NVD rates it 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), and the public record ties the issue to a crafted SMTP daemon response that sends an overlong 220 "Service ready" string, which can lead to arbitrary code execution.
