CVE-2018-16883
sssd versions from 1.13.0 to before 2.0.0 did not properly restrict access to the infopipe according to the "allowed_uids" configuration parameter.
Does this matter?
Lower severity and a low EPSS score (0.39%). Track it; it rarely justifies an emergency change on its own.
Description
sssd versions from 1.13.0 to before 2.0.0 did not properly restrict access to the infopipe according to the "allowed_uids" configuration parameter. If sensitive information were stored in the user directory, this could be inadvertently disclosed to local attackers.
