    Package : opensmtpd
    CVE ID : CVE-2020-7247
    Debian Bug : 950121

    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.

    For the detailed security status of opensmtpd please refer to
    its security tracker page at: https://security-tracker.debian.org/tracker/opensmtpd
