"The UNIX pipe which sudo uses to contact SSSD and read the available
sudo rules from SSSD has too wide permissions, which means that anyone
who can send a message using the same raw protocol that sudo and SSSD
use can read the sudo rules available for any user.

For Debian 8 'Jessie', these problems have been fixed in version
1.11.7-3+deb8u1.

We recommend that you upgrade your sssd packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
