Rocky Linux 8 : postgresql:13 (RLSA-2023:4527)

high Nessus Plugin ID 182723

Synopsis

The remote Rocky Linux host is missing one or more security updates.

Description

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2023:4527 advisory.

- schema_element defeats protective search_path changes; It was found that certain database calls in PostgreSQL could permit an authed attacker with elevated database-level privileges to execute arbitrary code. (CVE-2023-2454)

- Row security policies disregard user ID changes after inlining; PostgreSQL could permit incorrect policies to be applied in certain cases where role-specific policies are used and a given query is planned under one role and then executed under other roles. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications. This affects only databases that have used CREATE POLICY to define a row security policy. (CVE-2023-2455)

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

Solution

Update the affected packages.
