CVE-2018-10852 is fixed in 27 products on 1 platform, first by libipa-hbac0 1.16.1-1ubuntu1.8, released August 15, 2021. It is not reported as exploited. Patch Radar priority: Routine.
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. This affects versions of SSSD before 1.16.3.
