Linux Distros Unpatched Vulnerability : CVE-2019-13565

high Nessus Plugin ID 222486

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- 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 Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
