Detail
Qualys discovered that the OpenSMTPD SMTP server performed insufficient validation of SMTP commands, which could result in local privilege escalation or the execution of arbitrary code. For the oldstable distribution (stretch), this problem has been fixed in version 6.0.2p1-2+deb9u3. For the stable distribution (buster), this problem has been fixed in version 6.0.3p1-5+deb10u4. We recommend that you upgrade your opensmtpd packages.
