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
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
