Alpine: libldap, multiple openldap packages: security update to 2.4.48-r0

high Tenable Cloud Security Plugin ID 424294

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - 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.) (CVE-2019-13057)

 - An issue was discovered in OpenLDAP 2.x before 2.4.48. When using SASL authentication and session
 encryption, and relying on the SASL security layers in slapd access controls, it is possible to obtain
 access that would otherwise be denied via a simple bind for any identity covered in those ACLs. After the
 first SASL bind is completed, the sasl_ssf value is retained for all new non-SASL connections. Depending
 on the ACL configuration, this can affect different types of operations (searches, modifications, etc.).
 In other words, a successful authorization step completed by one user affects the authorization
 requirement for a different user. (CVE-2019-13565)
