"Sympa, a modern mailing list manager, allows privilege escalation
through setuid wrappers. A local attacker can obtain root access.

For Debian 9 stretch, this problem has been fixed in version
6.2.16~dfsg-3+deb9u3.

We recommend that you upgrade your sympa packages.

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