[SECURITY] [DLA 1429-1] sssd security update

Package : sssd
Version : 1.11.7-3+deb8u1
CVE ID : CVE-2018-10852
Debian Bug : 902860

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.
