Name of the Vulnerable Software and Affected Versions sssd versions 1.13.0 through 1.99.99 (since 2.0.0 is the first version not affected, it implies versions before 2.0.0 are vulnerable)

Description The issue concerns improper restriction of access to the infopipe based on the allowed uids configuration parameter. This could lead to the disclosure of sensitive information stored in the user directory to local attackers.

Recommendations For sssd versions 1.13.0 through 1.99.99, update to version 2.0.0 or later to properly restrict access to the infopipe according to the allowed uids configuration parameter.
