Qualys discovered that the OpenSMTPD SMTP server performed insufficient validation of email addresses which could result in the execution of arbitrary commands as root. In addition this update fixes a denial of service by triggering an opportunistic TLS downgrade.

For the oldstable distribution (stretch), these problems have been fixed in version 6.0.2p1-2+deb9u2.

For the stable distribution (buster), these problems have been fixed in version 6.0.3p1-5+deb10u3. This update also includes non-security bugfixes which were already lined up for the Buster 10.3 point release.

We recommend that you upgrade your opensmtpd packages.
