Qbik WinGate SMTP server denial of service
|qbik-smtp-dos (35950)||Medium Risk|
Qbik WinGate is vulnerable to a denial of service, caused by a format string vulnerability when the SMTP server component improperly handles an SMTP client session. By persuading a victim to connect to an SMTP server, a remote attacker could send a specially-crafted SMTP command containing malicious format specifiers to crash the process.
