CBL Mariner 2.0 Security Update: postgresql (CVE-2023-5870)

medium Nessus Plugin ID 211748

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of postgresql installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-5870 advisory.

 - A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue May allow a remote high privileged user to launch a denial of service (DoS) attack. (CVE-2023-5870)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
