EulerOS 2.0 SP3 : openldap (EulerOS-SA-2019-2640)

high Nessus Plugin ID 132175

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the openldap packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

- 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected openldap package.
