ldap-utils: An issue was discovered in the server in OpenLDAP before 2.4.48
CVE-2019-13057 is fixed in 5 products on 1 platform, first by ldap-utils 2.4.45+dfsg-1ubuntu1.3, released July 25, 2019. It is not reported as exploited. Patch Radar priority: Routine.
An issue was discovered in the server in OpenLDAP before 2.4.48. When the server administrator delegates rootDN (database admin) privileges for certain databases but wants to maintain isolation (e.g., for multi-tenant deployments), slapd does not properly stop a rootDN from requesting authorization as an identity from another database during a SASL bind or with a proxyAuthz (RFC 4370) control. (It is not a common configuration to deploy a system where the server administrator and a DB administrator enjoy different levels of trust.)
